One-Quadrant Chopper Control
This example shows how to control a one-quadrant chopper. The Control subsystem implements a simple PI-based control algorithm for controlling the output current.

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 10 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.
