Control and Simulate Torque of IPMSM in DQ Frame
Control the torque in an automotive electrical traction drive of an interior permanent magnet synchronous machine (IPMSM). The example controls and simulates the torque in the rotor direct-quadrature (DQ) reference frame. You can use the DQ reference frame to design the controller and to speed up the simulation. The IPMSM operates in both motoring and generating modes according to the load. An ideal angular velocity source provides the load. The Control subsystem uses an open-loop approach to control the IPMSM torque and a closed-loop approach to control the current. The control algorithm converts the torque request to the relevant current references. The reference DQ voltages feed the IPMSM. The simulation involves several torque steps in both motor and generator modes.
Control Torque of IPMSM Inside Axle-Drive EV in DQ Frame
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.

Models a simplified parallel hybrid electric vehicle (HEV). An interior permanent magnet synchronous machine (IPMSM) and an internal combustion engine (ICE) provide the vehicle propulsion. This 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 torque commands. A Stateflow® chart implements the vehicle control strategy. The ICE Controller subsystem controls the torque of the combustion engine. The EM Controller subsystem controls the torque of the IPMSM. 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.
