All discrete sample times in your model must be an integer multiple of the local solver sample time.

Anyone solve my Error:

Hi

If you do discrete steps simulation , simulink work at the highest sampling rate specified in your model.

You can have slower tasks, but those tasks time stamps must coincide with the time stamps of the higher sampling rate.

That's why all tasks must be running at nteger multiple of the local solver sample time.

example : fast task requires dt = 1e-3 , slower task 1 runs at dt1 = 10*dt, even slower task 2 runs at dt2 = 100*dt, etc...

look at the help for task rate transition between blocks running at different rates

Simulating a discrete system requires that the simulator take a simulation step at every sample time hit. For a multirate discrete system (a system whose blocks Simulink samples at different rates) the steps must occur at integer multiples of each of the system sample times. Otherwise, the simulator might miss key transitions in the states of the system.

You can resolve the error by setting the sample times of different blocks as integer multiples of solver’s sample time.
