how to overcome this error? The "FixedStepDiscrete" solver cannot be used to simulate block diagram 'Power_PMS​M_Drive_Di​agram_comp​lete' because it contains continuous states?

This tells you that some states in the model are continuous states. It can be a continuous integrator, or powergui block set to continuous time. When the model has continuous states a discrete solver cannot be used. However, we can still use other solvers such as ode14x, ode1 to ode8, auto. If you need to use "FixedStepDiscrete" then the option is to discretize the model and ensure there are no continuous states.
