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.

Results from Real-Time Simulation
This example has been tested on these platforms:
Speedgoat™ Performance real-time target machine with an Intel® 3.5 GHz i7 multi-core CPU and 4 GB RAM.
dSPACE® SCALEXIO LabBox with Intel® Core XEON E3-1275v3 at 3.5GHz and 4 GB RAM.
You can run this model in real time with a step size of 50 microseconds by using the Simscape local solver. For small sample rates, a task overrun might occur during the initial task execution due to a cold cache. To avoid this overrun, if the selected platform supports these options, relax the start-up behavior by specifying a limited number of task overruns or increasing the sample time of periodic tasks during the start-up phase of the real-time application.
