摘　　要：以工程中的伺服控制系统为研究对象,提出一种嵌入比例因子的复合模糊自适应PID控制方法,即将比例因子模糊控制与模糊PID控制结合而成的复合模糊控制。首先通过MATLAB/Simulink系统工具对无干扰理想状况下的系统进行仿真与分析,然后进一步模拟真实环境下的系统运行状况,在某一时刻加入干扰信号,并将比例因子模糊控制嵌入模糊PID控制中优化算法,对控制系统不断加以改善与优化。试验结果表明,此方法比传统PID控制更具优势,能有效改善控制系统的响应时间、调节时间以及抗干扰能力,有效提高控制系统的动态性能和鲁棒性。A compound fuzzy adaptive PID control method was proposed for the servo control system in engineering.This method bounded proportional factor fuzzy control and fuzzy PID control.Firstly,the analog simulation and analysis was taken for the ideal system with no interference through the MATLAB/Simulink.Then the simulation was taken with interference signal at a time and integrating the proportional factor and fuzzy PID control,to imitate the real situation of system operation and continue to improve the control system.The experiment shows that this method possesses more advantages compared with traditional PID.It can effectively ameliorate the response time,adjustment time,anti-interference ability,improve the dynamic performance and robustness of the control system.
