DiffEqs: Hybrid (continuous+discrete) system / periodic callback

What would be a good way to implement this? Basically, it would have to be something like tstops every second, but then pause the solver and let the discrete function (the controller algorithm) execute and change parameters and/or some state variables with zero autonomous dynamics. Is a DiscreteCallback the way to go?

Yup, tstops + DiscreteCallback is a good way to do it. Or just use the integrator interface.
