零极点配置智能PID控制器在系统控制中的应用

Application of intelligent PID controller of zero-pole placement in control system

为解决未知系统的PID控制问题,根据PID控制及零极点配置控制理论,详细讨论了零极点配置PID控制器、智能PID控制器的构成过程.该控制器结构简单,实用性强,控制器的阶数仅与被控系统的传递函数分子多项式阶数m有关,而与分母多项式阶数n无关,可以用低阶控制器控制高阶系统,通过大量的仿真试验研究,说明该智能控制器具有良好的自适应性和鲁棒性.

To resolve the PID control problem of unknown systems, intelligent PID controller of zero-pole placement was designed according to PID control system theory and zero-pole placement theory. This controller has simple structure and good practicability. Its order is only related to the order of controlled system＇ s denominator, and has no relationship to the numerator＇ s order. It is possible to use a low-order controller to control the actual higher-order system. Its robustness and adaptive character were well proved through lots of simulations and experiments.
