Simulating the Induction Motor Drive

Run the simulation by selecting Start from the Simulation menu in Simulink. The simulation parameters in the Simulation Parameters menu can be set as follows:

Simulation time: Start Time:0, Stop time: 1.5
Solver option: Type: Variable-step ode23tb (stiff/TR-BDF2)
Max Step Size: auto
Initial Step Size: auto
Relative Tolerance: 1e-3
Absolute Tolerance: 1e-3

The motor voltage and current waveforms as well as the motor speed and torque are displayed on three axes of the scope connected to the variables Vab, Is, Te, and .

Once the simulation is complete, return to the MATLAB command window to examine the results with more details by using the plot instruction.
