The integrator in the model was replaced by a first-order lag, the steady-state performance of the system was improved, the time-delay term in the model was approached with the first-order Taylor expansion, and the design method of IMC-PID controller was founded. The analytical expression for robust tuning the adjustable parameter of the IMC-PID controller was derived based on the robustness index of the control system. The simulation results showed that the proposed method could provide a better dynamic performance and robustness against parameters perturbation, and the blindness of conventional method for controller parameter tuning was overcome %K 鲁棒性 %K 动态响应 %K 积分时滞对象 %K 内模PID %K 参数整定 %K < %K br> %K dynamic response %K internal model control-PID %K integral process with time-delay %K robustness %K parameter tuning %U http://gxbwk.njournal.sdu.edu.cn/CN/10.6040/j.issn.1672-3961.0.2015.407
