Hi, Im trying to model a synchronous machine. My present situation is, i know the A, B, C, D values and my input signal is coming from other blocks which are voltages, speed etc. State variable in my case is flux. I need to find this flux value so as to find derive current, torque etc. So how to solve this state space equation to get the state variable. I tried to read many examples but im not able to find the one I need. Any help is appreciable

If you already know the A, B, C, D matrices, why not use a State-Space Simulink block, then?

Hi @Mahmoud Aly
For single-variable systems such as , you can use the Fcn block to apply the nonlinear function to its input (state variable x and input signal u). After that, connect the Fcn block to an Integrator block, which implies the output . Before clicking the Run button, specify the initial value in the Integrator block.
For multivariate systems, , with the state vector and input vector , you can use n sets of Fcn and Integrator pairs, or one MATLAB Function block and an Integrator block.
