Fuzzy controller and observer design for nonlinear system-LMI method
A fuzzy controller and observer design for a nonlinear system are studied based on LMI. The global asymptotically stable fuzzy controller and observer is gained, using the T-S fuzzy dynamic model approaching a nonlinear system and using a parallel distributed compensation method. The parameters of the fuzzy controller and fuzzy observer are obtained by the convex optimal method of LMI. The simulation of an inverted pendulum tested the efficiency of the design method.
