摘要
研究了一种误差驱动型自适应模糊PID控制器在二阶时滞系统中的应用。选择系统的稳态误差和误差变化率为PID参数自适应模糊调整的前件变量,将前件变量模糊化为7个论域期间,建立了PID参数调整的模糊规则表,查表得PID参数的后件参数,采用极大值反模糊化规则得到具体PID控制参数。仿真结果表明采用该控制器后系统的调节时间大大缩短,控制效果令人满意。
An error-driven adaptive fuzzy PID controller and its application in time-delay system are studied. According to the knowledge of experts and the influence of PID parameters on system, fuzzy rule tables are established. Comparing with the system with normal PID controller, the simulation results reveal that the time for stabilizing is greatly shorten.
