Control Approaches of Motor using Ansys SCADE Software — Lesson 3

This lesson covers motor speed control using Ansys SCADE® embedded software product collection, starting with a direct feed-through approach where motor speed directly affects PWM, but lacks feedback control, making it sensitive to load changes. A hand-coded proportional (P) control example is discussed, though it lacks monitoring, which Ansys SCADE software addresses. The focus is on implementing P control in Ansys SCADE software with monitoring to maintain constant speed under varying loads. The lesson shows how Ansys SCADE software adjusts the PWM signal based on speed differences and handles negative values.The lesson also covers proportional-integral (PI) control, explaining integration and the use of limiters to prevent wind-up. A visual comparison highlights how PI control recovers faster from load changes. Ansys SCADE Onemodel-based embedded software development solution is introduced as an alternative environment and encouraged to explore and test different control methods.
