Model Reference Switching Quasi-LPV Control of a Four Wheeled Omnidirectional Robot

Abstract

In this paper, the problem of trajectory tracking for a four wheeled omnidirectional robot is solved in the inertial fixed coordinate system. The solution relies on a reference model approach, where the resulting nonlinear error model is brought to a quasi-Linear Parameter Varying (LPV) form suitable for designing an LPV controller using Linear Matrix Inequalities (LMI)-based techniques. In particular, the controller is obtained within the switching LPV framework. The effectiveness of the proposed approach is shown through simulation results.
