DATA-DRIVEN BASED CONTROLLER DESIGN AND ITS PARAMETERS TUNING METHOD

A class of data-driven based controller design and its parameters tuning method (IFT-MFAC) was proposed for a class of discrete-time nonlinear system in this paper.Three controller structures are deduced according to non-parameters time-varying dynamic linearization theorem,then the controller parameters are tuning by IFT technique.The rationality of the 3 structures of the controller is assured by the theorem,whereas,the controller structure is designed blindly by IFT.Obviously,the new method settles down this problem more properly. Finally,the three data-based methods IFT-MFAC,MFAC and IFT were compared through 3 examples.And the simulation results show the validity of the IFT-MFAC.
