摘要
为了解决常规PID参数调节在非线性、时变和滞后性的工业控制系统中适应性能差、效果不理想的问题,采用模糊控制策略对PID控制参数进行在线自整定。利用Matlab的Simulink仿真工具箱对一阶惯性环节的滞后系统进行仿真研究试验,表明模糊参数自整定控制效果在超调量和调节时间上都优于常规的PID控制,改善了系统的动态性能。
Abstract： To solve the problems of bad adaptive performance and not ideal effect when conventional PID control is used in nonlinear and time-varying industrial systems with time delay, fuzzy control strategy is adopt to selftune PID parameters online. The simulation and experiments on one order inertia system with time delay, show that fuzzy parameters self-tuning control is better than the conventional PID control in overshoot and tuning time, and can improve the dynamic performance.
