摘要

对积分加死区系统(IPDT)控制中不同的两自由度(2DOF) PI控制器整定方法[1]的比较表明，基于性能画像法的新工具具有显著的最优鲁棒整定优势。现在，通过考虑工厂参数的不确定性和推导相应闭环的鲁棒性特性，进一步扩展所提出的分析，该闭环表示参数不确定性对指定形状要求下所选性能测量的影响。

Robustness characteristics and optimal robust tuning of a 2DOF PI control for an uncertain IPDT plant

A comparison of different two degree of freedom (2DOF) PI controller tuning methods [1] in control of an integral plus dead time system (IPDT) showed significant advantages of the new tool for an optimal and robust tuning based on the performance portrait method. The presented analysis will now be further extended by considering uncertainties of both plant parameters and by derivning robustness characteristics of the corresponding closed loops expressing influence of a parameter uncertainty on a chosen performance measure under specified shape requirements.
