Control of PMSMs with Double Loop Data-Driven Techniques

In this paper the data driven technique known as Model-Free Adaptive Control is applied to the speed tracking problem for a Permanent Magnet Synchronous Motor. Inspired by previous literature, a novel theoretical analysis is here presented allowing to consider time-varying reference variables for the motor. In particular a stability analysis is proposed, proving the boundedness of the tracking error and the Bounded-Input-Bounded-Output stability of the closed-loop system for two different double loop control configurations. Simulation results are reported showing the effectiveness of the proposed approaches. This work is a preliminary study preceding the experimental validation of the proposed control solutions, currently ongoing.
