Abstract: This paper addresses the stabilisation problem of nonholonomic mobile robot with two trailers. A discontinuous control law is built after a suitable change of variables to achieve a quasi-exponential convergence of the system variables to the origin. Particle Swarm Optimisation technique is used to tune the controller parameters for optimised transient performance under constrained control signals. Simulation results are presented to illustrate the effectiveness of the presented approach.

Keywords: nonholonomic systems; particle swarm optimisation; PSO; quasi-exponential stabilisation; nonholonomic robots; wheeled robots; mobile robots; trailers; discontinuous control; robot control; simulation.
