Abstract : "An anti-windup controller for multi-input nonlinear system is proposed in this paper. The proposed
method does not need to calculate every time for every fuzzy rules comparing with traditional linear pole placement
of T-S(Takagi-Sugeno) fuzzy. This means fewer LMIs(linear matrix inequality) will be needed and its solution
will be guaranteed as much as possible. For different saturation limit, different D-stable disk center and radius of
pole placement can be selected to eliminate input saturation effect directly. Nonlinear system will be transferred
to T-S fuzzy model first. Then, by employing a series of transition matrix, nonlinear system will be transferred
into a nearly linear format accompanied by a nonlinear part. Finally, by designing a proper controller, linear pole
placement method can be used and the controller gains can be calculated out with LMIs."
