摘要

在过程工业中，需要有鲁棒控制器，以便即使在存在干扰的情况下也能获得所需的响应。本文考虑SOPDT模型，并针对其设计了PID控制器。通过模型参数的摄动来检验PID控制器的鲁棒性。对模型参数K(增益)、τ1、τ2(时间常数)进行了15%的扰动，并将扰动后系统的响应与原系统的响应进行了比较。

Modeling error effect on performance of a second order delayed process model

In a process industry it is desirable to have robust controller so that required response is obtained even in the presence of disturbances. In this paper, SOPDT model is considered and PID controller is designed for it. Robustness of PID controller is checked by perturbation of model parameters. Model parameters K (gain), τ1, τ2 (time constants) are perturbed by 15% and response obtained for perturbed system is compared with that of original system.
