一种新的积分过程PID控制器整定方法

针对积分过程，提出了一种简单、实用的PID控制器。该方法首先通过PD控制器对积分过程建立内部反馈控制回路，将内部闭环系统近似为二阶加纯滞后模型；然后，根据有效的模型，基于鲁棒性能指标设计外部反馈回路的PID控制器；最后，简化控制系统的结构，采用设定值加权PID控制器控制积分过程。仿真结果表明了设定值加权PID控制器的有效性和可行性。

A New Tuning Method of PID Controller for Integrating Processes

It proposes a simple and effective PID controller for integrating processes.It first introduces an inner feedback loop for integrating processes through PD controller,and the loop system is approximated to a second-order plus time delay model.Then,with the available model,PID controller is designed on the basis of robust specification.At last,controller structure is simplified and PID controller with set-point weighting is used to control integrating processes.Simulation examples show the effectiveness and feasibility of PID controller with set-point weighting.
