摘要
基于实际控制对象模型的不确定性,本文运用鲁棒控制理论,对PID控制系统的鲁棒性进行了讨论,提出了鲁棒PID控制器的一种设计方法。实际控制系统的仿真结果表明,此设计方法简单且具有一定的工程实用性。
Based on the uncertainty of the model of the plant, the robustness of the PID control system is discussed by using the robust control theory, and a method of the design for robust PID controller is stated. The simulation result of the practical control system shows that the method of the design is simple and practical in engineering.
