ControlSystem with parameters

[AlCap23]

I have problems implementing a ControlSystem conversion in DataDrivenDiffEq ( SciML/DataDrivenDiffEq.jl#158 ).

I think it boils down to adding parameters to the problem. Is this a known limitation right now?

A MWE would be

using ModelingToolkit

@variables t x(t) v(t) u(t)
@parameters p
@derivatives D'~t

loss = (4-x)^2 + 2v^2 + u^2
eqs = [
    D(x) ~ v
    D(v) ~ p*u^3
]

sys = ControlSystem(loss,eqs,t,[x,v],[u],[p])
runge_kutta_discretize(sys, 0.1, (0.0, 1.0))

Which gives
