Abstract

It is known that the equation of motions for an omnidirectional mobile robot is nonlinear with respect to the rotational angle between the moving and absolute coordinate systems. In this paper, a fuzzy model approach is applied to the control of a time-varying rotational angle, in which multiple linear models are obtained by utilizing the original nonlinear model in some representative angles and they are used to derive the optimal type 2 servo gain matriees. The effectiveness of the proposed method is illustrated by giving some simulations for the trajectory tracking control problem.
