Control Torque of IPMSM Inside Parallel HEV in DQ Frame
This example 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.
