Sliding Mode Control for Nonholonomic Mobile Robot

چکیده

Abstract A new control scheme is presented for nonholonomic mobile robots. The main idea of this paper is to consider the natural algebraic structure of the chained form system together with ideas from sliding mode theory while designing the control law. At first, the system model is converted into a single-input time-varying linear system by setting one input as a time-varying function. We design the sliding mode control law by using pole placement based on pseudo-linearized model. The point stabilization and path-tracking problem for chained form are studied based on these ideas. Simulations for both unicycle car and car like robot showed this control algorithm can make the mobile robot stabilized at desired configuration and following the desired trajectory with a high precision.

Robust Sliding Mode Controller for Trajectory Tracking and Attitude Control of a Nonholonomic Spherical Mobile Robot

Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...
