Sc. Tong et Ty. Chai, Direct adaptive control and robust analysis for unknown multivariable nonlinear systems with fuzzy logic systems, FUZ SET SYS, 106(3), 1999, pp. 309-319
In this paper, we are dealing with the problem of controlling an unknown no
nlinear dynamical system modeled by fuzzy logic systems. In the ideal case
of complete model matching, convergence of the state to zero plus boundedne
ss of all signals in the closed loop system is ensured. Moreover, the robus
tness of the controller designed in the ideal case is given in the framewor
k of singular perturbation theory. (C) 1999 Elsevier Science B.V. All right
