In order to simulate a tracking problem with event-triggered control I think I need to use a Triggered Subsystem. Actually, the problem is that the trigger for the Subsystem depends on the output of the Triggered Subsystem. If I want to simulate the model it gives a loop error.

It is not possible for me to use the Latch option, otherwise the model isn't appropriate anymore.

I tried some things with the option 'state output' of the integrator block to avoid loop errors, but then there is the problem that everytime the trigger occurs the sample of the state has to be kept constant until the next trigger occurs.

Are there any alternatives to deal with this situation?
