IPOA-NLADRC Based Permanent Magnet Synchronous Motor Control Strategy

This paper proposes a method to improve the Pelican Optimization Algorithm (IPOA) to optimize the Nonlinear Active Disturbance Rejection Control (NLADRC) for the shortcomings of the traditional PI control in permanent magnet synchronous motors, which has a slow time to enter the steady state and a poor anti-jamming ability. The method utilizes the improved Pelican optimization algorithm for parameter tuning of in NLADRC, and finally, the superiority of the method for the entry steady-state response time as well as the anti-disturbance performance is demonstrated by comparing with the PI control and the Linear Active Disturbance Rejection Control (LADRC). The experimental results show that the optimized NLADRC based on IPOA has better control performance in terms of motor starting, variable speed and variable load, which effectively improves the response speed and anti-interference capability.
