摘要
the objective of this paper is to navigate an omnidirectional mobile robot from an initial point to a desired point with predefined direction with minimal error. For this reason, we apply the sliding mode control. Fundamentally, the conventional sliding mode control uses a switching control law to drive the nonlinear system trajectory onto a sliding surface in the system state space and to keep it on this surface. This leads to a chattering phenomenon. In order to overcome this problem, we develop the sliding mode control with a proportional integral (PI) tuning. Simulation results show the performances and the improvement of the second approach compared to the first one.
