Variable does not exist when it used in discrete_events but not in dynamics equation

[florian-die]

Hi,

I'm trying to connect a linear system with a sensor. The output of the sensor is continuous and updated at sampled times, it stays constant in between sampled times.

My issue is that in the dynamics equation of the sensor, the state and control of the linear system do not appear. They appear only in the discrete_events affect. This throws an error when I try to connect the sensor and the system.

The code is the following.

using ModelingToolkit
using DifferentialEquations

A = [0. 1. ; 0. 0.] # 2×2 Matrix{Float64}
B = [0. ; 1.0 ;;] # 2×1 Matrix{Float64}
C = [1.0 0.0 ] # 1×2 Matrix{Float64}
D = [0.0 ;;] # 1×1 Matrix{Float64}

x0 = [0.0 ; 1.0 ;;] # 2×1 Matrix{Float64}
u0 = [0.0 ;;] # 1×1 Matrix{Float64}

Δt = 1.0
tf = 10.0

y0 = C*x0 + D*u0 # 1×1 Matrix{Float64}

function linear_system(A,B;name)
    nx = size(A,1) 
    nu = size(B,2)

    @variables t x(t)[1:nx,1] u(t)[1:nu,1] 
    d_dt = Differential(t)

    eqs = d_dt.(x) ~ A * x + B * u 

    ODESystem(eqs;name)
end

@named system = linear_system(A,B)

function linear_sensor(C,D,Δt;name)

    nx = size(C,2)
    ny = size(C,1)
    nu = size(D,2)

    @variables t x(t)[1:nx,1] u(t)[1:nu,1] y(t)[1:ny,1]
    d_dt = Differential(t)

    eqs = d_dt.(y) .~ 0. 

    measure = y ~ C * x  + D * u

    update = [Δt => measure]

    ODESystem(eqs;name,discrete_events=update)
end

@named sensor = linear_sensor(C,D,Δt)

connections = [ Symbolics.scalarize(sensor.x ~ system.x) ;
                Symbolics.scalarize(sensor.u ~ system.u) ]

The error occurring at the last line

I tried it using DiscreteUpdate, inspired by

ModelingToolkit.jl/test/odesystem.jl

Lines 410 to 431 in 74e2571

	# Mixed Difference Differential equations
	@parameters t a b c d
	@variables x(t) y(t)
	δ = Differential(t)
	Δ = Difference(t; dt = 0.1)
	U = DiscreteUpdate(t; dt = 0.1)
	eqs = [δ(x) ~ a * x - b * x * y
	δ(y) ~ -c * y + d * x * y
	Δ(x) ~ y
	U(y) ~ x + 1]
	@named de = ODESystem(eqs, t, [x, y], [a, b, c, d])
	@test generate_difference_cb(de) isa ModelingToolkit.DiffEqCallbacks.DiscreteCallback
	# doesn't work with ODEFunction
	# prob = ODEProblem(ODEFunction{false}(de),[1.0,1.0],(0.0,1.0),[1.5,1.0,3.0,1.0])
	prob = ODEProblem(de, [1.0, 1.0], (0.0, 1.0), [1.5, 1.0, 3.0, 1.0], check_length = false)
	@test prob.kwargs[:callback] isa ModelingToolkit.DiffEqCallbacks.DiscreteCallback
	sol = solve(prob, Tsit5(); callback = prob.kwargs[:callback],
	tstops = prob.tspan[1]:0.1:prob.tspan[2], verbose = false)

It works as expected with a scalar state and when the system and sensor equation are merged into a single ODESystem

using ModelingToolkit
using DifferentialEquations

Δt = 0.1
tf = 1.0
c = 2.
x0 = 1.
y0 = 0.
X0 = [x0, y0]

@variables t x(t) y(t)

δ = Differential(t)

U = DiscreteUpdate(t; dt = Δt)

eqs = [ δ(x) ~ -x 
        δ(y) ~ 0. 
        U(y) ~ c * x ]

@named sys = ODESystem(eqs,t,[x,y],[])

pb = ODEProblem(sys, X0, (0.,tf),[], check_length = false)

sol = solve(pb, Tsit5())

using Plots

plot(sol)

However, I have an error when I try to split the system and the sensor into two ODESystems

using ModelingToolkit
using DifferentialEquations
using Symbolics

function system(a;name)
    @variables t x(t)
    δ = Differential(t)
    eqs = [δ(x) ~ a * x]
    ODESystem(eqs;name)
end

a = -1.
@named sys = system(a)

function sensor(c,Δt;name)
    @variables t x(t) y(t)
    δ = Differential(t)
    U = DiscreteUpdate(t; dt = Δt)
    eqs = [ δ(y) ~ 0. 
            U(y) ~ c * x ]
    ODESystem(eqs;name)
end

c = 2.
Δt = 0.1
@named sens = sensor(c,Δt)

connections = [sens.x ~ sys.x]

@named connected = ODESystem(connections)
    # Model connected with 1 equations
    # States (2):
    #   sens₊x(t)
    #   sys₊x(t)
    # Parameters (0):
    
@named sys_con = compose(connected,sys,sens)
    # Model sys_con with 4 equations
    # States (3):
    #   sens₊x(t)
    #   sys₊x(t)
    #   sens₊y(t)
    # Parameters (0):

sys_simp = structural_simplify(sys_con)

The error happens when calling structural_simplify and reads

[isaacsas]

ModelingToolkit currently can't auto detect parameters and variables that appear in events (unlike for the system's equations). Have you tried using the four-argument version of ODESystem where you pass the list of states and parameters explicitly, see https://docs.sciml.ai/dev/modules/ModelingToolkit/basics/Events/#Example:-Injecting-cells-into-a-population for examples that use that version of ODESystem.

[florian-die]

I'll try that, thanks for the advice =)

I am now able to simplify and solve, but it seems my callback has no effect because y is not updated every Δt

    @parameters Δt = Δt_
    @variables t x(t) y(t)

Maybe it is because the discrete event is using sens.x and not sys.x ?

I tried adding manually a periodic callback but it failed

function sensor_cb(int)
    int.u[2] = 2.0 * int.u[1]
end

pcb  = PeriodicCallback(sensor_cb, Δt)

prob = ODEProblem(sys_simp,X0,(0.0,tf),callback=pcb)

sol = solve(prob)

Thanks in advance for your help

In my previous comment I forgot to add the tstops to the ODEProblem, as in the tutorial, that's why y is not updated.

However when add the tstops then same ERROR: UndefVarError: sens₊x not defined reapears.

I guess it's because sens₊x was eliminated in the structural_simplify

[isaacsas]

structural_simplify does not check if a variable is used in an event currently, so you either need to avoid it, or tag the variables to not be removed. I've never done the latter, but @YingboMa in #1646 said it is achieved by setting the irreducible=true metadata for the variable (see that issue). You could give that a try and see if it helps.

[florian-die]

Following this I can remove the tstops if I change my discrete event as

function sensor(c_,Δt_;name)
    @parameters c = c_ 
    @parameters Δt = Δt_
    @variables t x(t) y(t)
    δ = Differential(t)
    update = [Δt => [y ~ c * x]]
    eqs = [ δ(y) ~ 0. ]
    ODESystem(eqs,t,[x,y],[c,Δt];
        name = name, 
        discrete_events = update)
end

but then I have this error when solving

julia> sol = solve(prob)

If I hard code the Δt, I get the previous ERROR: UndefVarError: sens₊x not defined

function sensor(c_,Δt_;name)
    @parameters c = c_ 
    @parameters Δt = Δt_
    @variables t x(t) y(t)

        discrete_events = update)
end

[florian-die]

structural_simplify does not check if a variable is used in an event currently, so you either need to avoid it, or tag the variables to not be removed. I've never done the latter, but @YingboMa in #1646 said it is achieved by setting the irreducible=true metadata for the variable (see that issue). You could give that a try and see if it helps.

I'll check, thanks again

[isaacsas]

I haven't used them, but I believe periodic and preset time events require numerical values for the times and don't work with symbolic values. If you want symbolic values you have to use the general discrete event interface and specify tstops.

[florian-die]

I can get the numerical value from the arguments of my sensor function.

Here is a working example that does what I want.

The only remaining bother is to specify twice the x initial condition because of the [irreducible=true].

Thanks a lot for your help @isaacsas 🎉 😄

Glad you got it working! There is definitely some work we need to do to cleanup the interaction between events and structural_simplify, and to make it easier to specify time-based events with symbolic parameters for dt and tstops.

[isaacsas]

You should always pass initial conditions and parameter values via mappings (as you do in the last example), or by specifying default values when you create the symbolic variable. You shouldn't generally use a purely numeric vector that assumes a specific variable ordering. The latter might break on you with changes to what is eliminated or how variables are reordered within ModelingToolkit.

I came back to my first post where I tried to do it using vector states, and I came upon an another "bug".

I have

• a system : a double integrator, with position and velocity as states, and acceleration as a control
• a "discrete" sensor which measures position and velocity, and updates its outputs every Δt
• a controller (static gain) that uses the measurements from the sensor

The system (top plot) and sensors (bottom plot) behave as expected. However, when I plot the control, I expect a step signal but a see some weird oscillations that I cannot explain.

It's weird because the control signal fed to the system seems correct because when looking at its velocity it's a ramp signal, that is coherent with a staircase acceleration (and its position is also quadratic looking curve).

For now it's not really a major issue because I can recompute the control with the sensor outputs.

Thanks in advance for your help =)

Maybe it is the control u=K*x computed with the continuous x variable, I see only that for now. I'll check.
