【摘要】 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.更多还原

【Abstract】 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.更多还原
