摘要
以输出误差e、误差积累Σe、误差变化率△e为控制器输入,设计了三输入单输出的T-S模糊PID控制器。针对时滞系统,分别采用传统PID控制器、Smith预估补偿器、T-S模糊PID控制器进行控制并仿真比较,结果表明:T-S模糊PID控制器具有控制精度高、响应快速、适应性强的特点;当时滞系统的时滞发生较大变化时,控制器仍具有很好的控制效果,系统稳定。
Three-input and single-output T-S fuzzy PID controller was designed with input according to output error,error accumulation and error change rate.Aiming at the time-delayed system,PID controller,Smith predicative and T-S fuzzy PID were separately addopted.The results of simulation indicate that the T-S fuzzy PID controller has the character of high precise,response speedy and flexibility.The system is still very stable when time-delayed of object occurred.
