A Two-Degree-of-Freedom IMC Parameters Online Intelligent Tuning Method

Focuses on the typical process in the industrial filed, a two-degree-of-freedom (TDOF) internal model controller was designed in this paper. It can independently adjust the target tracking performance, disturbance rejection properties and robustness. The on-line intelligent tuning method based on fuzzy neural network for the TDOF internal model controller was proposed. The theory analysis and simulation results show that the proposed method is simple, parameters tuning easy, and can make the system has a good target tracking performance, disturbance rejection properties and robustness.
