基于Taylor和Pade能逼近的滞后系统IMC-PID研究

Taylor and Pade IMC-PID

针对一阶加纯滞后过程,对滞后项分别进行Taylor逼近、一阶Pade逼近、二阶Pade逼近和全通逼近,设计出基于内模原理的PID反馈控制器,对其参数整定进行分析,并进行仿真实验,评价了各种PID控制器的适用情况.

For the first- order plus dead -time process, the dead -time part is carried on with Taylor approximation, first- order Pade approximation, second -order Pade approximation and all -pass approximation respectively to design PID feedback controllers based on internal model principle. The modifification of controllers parameters is analyzed and simulation test is done. A comment is made on the application of various PID controllets.
