一种积分时滞过程的内模PID鲁棒整定方法
IMC-PID robust tuning method for integrated process with time-delay
摘要
Abstract
For the integrated plus time delay in industrial system,a design and parameters tuning approach of internal model control-proportional integral derivative(IMC-PID) controller was proposed.Replacing the integrator in the model by a first-order lag,the steady-state performance of the system was improved.On this basis,the time-delay term in the model was approached with the first-order Taylor expansion.So,the design method of IMC-PID controller was founded.In addition,the analytical expression for robust tuning the adjustable parameter of the IMC-PID controller was derived by the maximum sensitivity specification Ms,and the blindness of conventional method for controller parameter tuning was overcome.The simulation results show that the proposed method can provide a better dynamic performance and robustness against parameters perturbation.关键词
