Abstract EN
The sliding mode control (SMC) strategy is employed to a permanent magnet synchronous motor (PMSM) vector control system in this study to improve system robustness against parameter variations and load disturbance.
To decrease the intrinsic chattering behavior of SMC, a speed SMC with an adaptive law and an extended state observer (ESO) is proposed.
In this method, based on the Lyapunov stability theorem, adaptive estimation laws are deduced to estimate uncertainties of a PMSM caused by parameter variations and unmodeled dynamics.
Online estimated uncertainties can be used to eliminate the effect caused by the real uncertainties.
In addition, an ESO is applied to observe the load disturbance in real time.
The load disturbance observed value is then utilized to the output side of the speed adaptive SMC controller as feed-forward compensation.
Both the simulation and experiment results demonstrate that the proposed approach effectively alleviates system chattering and enhances system robustness against uncertainty and load disturbance.
