摘要
设计了模糊PID(Proportion Integration Differentiation)控制器,在给定参数下利用MATLAB/Simulink对数字缸系统性能进行仿真分析,得到了不同输入信号下系统的响应特性。仿真结果表明:采用模糊PID控制比普通PID控制改善了数字缸系统动态性能,减小了超调量,提高了响应速度。
Firstly, a fuzzy PID controller is designed. By using MATLAB/SimulinkTM for simulation and analysis on digital hydraulic cylinder system, the system response properties towards different input sig- nals are then obtained under specific parameters. Finally, it is indicated from simulation results that, com- pared with traditional PID control, the dynamic properties of digital hydraulic cylinder system are improved using fuzzy PID control in terms of overshoot reduction and response speed enhancement.
