Abstract:

The traditional hierarchical sliding mode control method applied directly to the spherical robot speed control will cause a long adjustment time and a large overshoot， which is hard to meet the requirements in practical application. In this paper， a new sliding surface with fractional order PIλDμstructure is proposed by introducing a derivative element and fractional order calculus. The asymptotic stability condition of the sliding surface is given. Based on the new fractional PIλDμ sliding surface， a velocity controller for the linear motion of the spherical robot is designed. Furthermore， an adaptive law is used to estimate the unknown rolling friction. The simulation results show that the new adaptive fractional sliding mode controller designed in this paper presents a better control performance and stronger robustness compared to the conventional one. Besides， the new controller can accurately estimate the unknown rolling friction.

Key words: control theory, fractional sliding mode, spherical robot, speed control, adaptive control
