Abstract

The current constraint and robustness improvement of the speed-current single-loop controlled permanent magnet synchronous motor (PMSM) are investigated. To begin with, a speed-current single-loop control for PMSM is proposed based on a novel proportional integral derivative (PID) controller. Additionally, a barrier penalty factor is introduced in the differential term of the PID to constrain the q-axis current. Moreover, an adaptive extended state observer (AESO) is proposed to attenuate the peak problem and compensate for the mismatched disturbances of the non-cascade-controlled PMSM. A rigorous stability analysis is conducted for the proposed system. Finally, extensive comparative simulations and experiments are performed among the proportional-integral (PI), PI-based ESO (PI-ESO), sliding mode control (SMC), and the proposed strategy to demonstrate better transient performance and higher robustness. Parametric perturbation experiments further demonstrate the strong robustness of the proposed method.
