Simulating the Induction Motor Drive

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

• Simulation time: Start Time:0, Stop time: 1.5
  Solver option: Type: Variable-step ode23tb
  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 detail by using the plot instruction.
