I want to apply an external initial condition to my resettable system, just like how it is possible with a integrator block. Anyone know how to do that?

Use "Initialize Function" in library Simulink\User-Defined Functions.

But the state writer only works for discrete state space state owner. Is there any that works for continuous state space?

Integrator is supported. Not sure why continuous State-Space is not supported. If dropping a continuous State-Space block, the StateWriter block seems to "see" it. I didn't try to see if it actually works.

would this be the correct way to implement it? The state space will reset when the resettable subsystem experiences a reset event (its "either" input becomes true)

No longer need to use "Resettable Subsyhstem"
  1. Construct your regular Subsystem with states
  2. Construct your reset logic to send a "reset" event, which trigs the "Reset Function"
  3. Inside your "Reset Function", construct those reset values and write to the states.
Take a look at the built-in demo models.
