Adaptive fuzzy dynamic surface control of unknown multivariable nonlinear systems
In this paper, by using backstepping technique, the adaptive fuzzy dynamic surface control problem is discussed for a class of unknown multivariable nonlinear systems which the control gains are unknown. By the special design scheme, the ldquoexplosion of complexityrdquo problem is avoided. Furthermore, the closed loop signals are guaranteed uniformly ultimate boundedness, and the tracking error arbitrarily small.
