Fuzzy indirect adaptive output tracking control of nonlinear systems. (English) Zbl 0988.93051
The paper is concerned with the design of a fuzzy controller for a single input single output system described in the following form $$x^{(n)}= g(x,x', \dots, x^{(n-1)})u \qquad y=x.$$ The fuzzy controller is realized using a center-of-average defuzzifier, product-based inference and can be represented as $y(x)= p^Tv(x)$ with $p$ being a vector of parameters and $v(x)$ resulting from the fuzzy basis functions used in the antecedent part of the fuzzy controller. As the system is unknown, the authors propose a control $u=u_1+u_2$ with $u_1$ being the output of the equivalence controller and $u_2$ standing for the robust compensator. The design of the controller is discussed and its tracking performance analyzed.
