摘要
以数控机床进给伺服系统为研究对象,结合模糊控制和PID调节的各自优点,分析研究模糊PID控制器的实现方法。运用MATLAB建立应用模糊PID控制的伺服系统仿真模型,对模糊PID控制器的设计方法与应用效果进行了研究探讨。仿真实验结果表明模糊PID控制器能够很好的弥补常规PID控制整定不良、性能欠佳和适应性差的缺点,有效地减少了系统响应的超调,具有良好的动态特性。
In order to study fuzzy PID controller method,the NC machine tool servo system was introduced as a study object and has analyzed the advantages of fuzzy controller and PID method.By using the MATLAB and Simulink environment to build a simulation of fuzzy PID controller,one design procedure of fuzzy PID controller and its applications were studied.The simulation result showed that fuzzy PID controller can make up the deficiencies of conventional PID controller which has poor performance and poor quality of adaptability relatively,and fuzzy PID controller can reduce the overstrike of system with good dynamic response and dynamic characteristics.
