This paper discusses the tracking problem of dynamic wheeled moving robot (WMR) subject to nonholonomic constraints and actuator saturations. A constrained guaranteed cost tracking scheme for this problem via Tagaki-Sugeno (T-S) fuzzy model is proposed, where tracking error dynamics of WMR is represented by T-S fuzzy model which are dynamic combination of several linear sub-systems, and then constrained guaranteed controller in the form of state feedback is derived for each subsystem by solving LMI based semi-definite programming problems. The overall controller then is constructed in the framework of PDC and the Lyapunov stability of the closed-loop system is tested finally. Simulation results are given and discussed to validate the proposed scheme.
