Abstract :
The paper proposes an auto-tuning algorithm for a DSP-based permanent magnet synchronous motor (PMSM) drive. In order to be compatible with the conventional drives, the proportional-plus-integral (PI) speed control with gains individually designed by Bode diagram and an extension of the frequency-zone method to decouple the tuning gains in a multiloop control system is studied. The auto-tuning scheme includes two steps, an adaptive load observer to estimate the load inertia and adaptive two-degree-of-freedom PI tuning. Finally, the experimental results of estimating some known inertia loads and square wave speed responses have verified the effectiveness of the proposed auto-tuning algorithm.
