Field oriented control has proven effective for controlling AC drives with good dynamic performance. However, operation at low switching frequencies and sensitivity of traditional feed-forward loops to system parameters pose severe limitations on the achievable performance and require a tedious tuning procedure. In this work, we present a systematic cascade explicit model predictive control framework for field-oriented control of electrical drives, resolving the aforementioned issues while being sufficiently simple to be widely implemented on various AC drive systems. The resulting closed-loop system exhibits high dynamic performance for all operating points, even at low switching frequencies. We present experiments with a permanent magnet machine and an induction motor, demonstrating the practical feasibility and the merits of the proposed framework over traditional controller designs for electrical drives.
