Analysis of Mold Demolding System with Tracking Differential Fuzzy PID Compound Control
摘要
Abstract
This study addresses control challenges in mold demolding systems under nonlinear and time-varying load conditions.A tracking differential fuzzy PID compound control strategy is proposed to enhance system performance by integrating tracking differentiator technology with fuzzy PID control.The strategy features rapid error signal tracking and dynamic self-tuning of PID parameters.The co-simulation experiments combining AMESim and Simulink validate the proposed method.The results demonstrate significant improvements over conventional PID and fuzzy PID controllers:reduced response lag and steady-state error,enhanced tracking precision under high-frequency noise and superior disturbance rejection against unknown large-load interference.The control strategy maintains stable performance in complex operating environments while achieving faster dynamic response.These findings provide theoretical support for high-precision hydraulic servo control in mold demolding systems,particularly in scenarios requiring robust adaptability to nonlinear disturbances.The proposed method offers a practical solution for optimizing industrial mold demolding processes with time-varying dynamics.关键词
