摘 要：正A new indirect adaptive fuzzy control scheme is developed for a class of nonlinear discrete-time multi-input multi-output *** avoid the possible controller singularity problem,the controller,which is designed by fuzzy logic systems,is derived from quadratic performance index,and the time-varying gain adaptive laws are used to adjust the unknown parameters. The proposed design scheme guarantees that all the signals in the resulting closed-loop system are bounded,and the the estimated value of generalized tracking error converges to a small neighborhood of the origin.
