摘要
This job focuses on the stroke regulation of a class of high-precision metering pumps.A parametertuning method of robust non-fragile PID（proportional-integral-derivative）controllers is proposed with the assumption that a PID controller has additive gain perturbations.An H-infinite robust PID controller can be obtained by solving a linear matrix inequality.This approach can guarantee that the closed-loop control systems is asymptotically stable and the H-infinite norm of the transfer function from the disturbance to the output of a controlled system is less than a given constant to attenuate disturbances.The simulation case shows that the control performance of the proposed strategy is significantly better than the traditional PID approach in the situation with perturbations of controller parameters.
这个工作准时集中高精确的 metering 泵的一个班的规定。柔韧的非易碎的 PID (proportional-integral-derivative ) 控制器的一个调节参数的方法与假设被建议一个 PID 控制器有添加剂获得不安。一个 H 无限的柔韧的 PID 控制器能被解决线性矩阵不平等获得。这条途径靠近环的控制系统是 asymptotically 稳定的保证和转移的 H 无限的标准能从骚乱工作到一个控制系统的输出不到稀释骚乱的一个给定的常数。建议策略的控制表演比传统的 PID 显著地好的模拟盒子表演与控制器参数的不安处于状况来临。
