Control Torque of IPMSM Inside Axle-Drive EV in DQ Frame

Since R2025a

This example models an interior permanent magnet synchronous machine (IPMSM) propelling a simplified axle-drive electric vehicle. The example controls and simulates the torque in the rotor direct-quadrature (DQ) reference frame. The IPMSM operates in both motoring and generating modes. A fixed-ratio gear-reduction model implements the vehicle transmission and differential. The Vehicle Controller subsystem converts the driver inputs into a relevant torque command. The Drive Controller subsystem controls the torque of the IPMSM. The control algorithm is implemented in continuous time. To simulate this model faster, this example uses a variable-step solver. The Scopes subsystem contains scopes that allow you to see the simulation results.
