摘要
本文分析了过程控制中广泛应用的 PID 控制系统的鲁棒性,得出了 PID 控制系统鲁棒稳定的必要条件并指出了 PID 调节器的局限性.本文提出了一种采用约束寻优方法选取 PID 参数的方法,该方法兼顾了性能指标和鲁棒性要求.这种设计方法直接考虑了模型不确定性函数,设计出具有明确鲁棒性范围的控制系统.
The paper analyzed the robustness of PID control systems widely used in process control,gave a neces-
sary condition for robust stability and pointed out the limitation of PID regulators.The paper proposed a
method for choosing PID parameters throuth constrained optimization,which gives consideration to both
performance and robustness.A function of model uncertainty is used to design a robust control system
Which is stable within the prescribed region of variations of transfer function.
