基于模糊PID与自抗扰的织针直驱直线电机控制
Control of direct drive linear motor for knitting needles based on fuzzy PID and active disturbance rejection
摘要
Abstract
Aiming at the problem of insufficient stability of the direct-drive ultra-thin linear motor for knit-ting needles when facing load disturbances and parameter variations,a composite control strategy integrating ac-tive disturbance rejection control(ADRC)and fuzzy PID control is proposed.This strategy utilizes Fuzzy PID control to overcome the limitations in parameter tuning of traditional PI controllers,thereby enhancing their adaptability and robustness.Moreover,to compensate for disturbances caused by sudden load changes and pa-rameter fluctuations within the control system,ADRC is introduced.It employs an Extended State Observer(ESO)to monitor and estimate the dynamic behavior and parameter variations of the current loop in real-time,providing the control system with accurate state information and parameter estimation for effective disturbance rejection.The effectiveness of the proposed control strategy has been validated through simulation analysis and prototype testing.Findings indicate that under sudden load conditions,the speed fluctuation error is reduced by 64.3%compared to traditional PI control and by 57.7%compared to Fuzzy PID control.Additionally,during pa-rameter variations,the speed error is decreased by 35.6%compared to Fuzzy PID control alone.This composite control strategy significantly enhances the control performance and disturbance rejection capabilities of ultra-thin linear motors.关键词
