Adaptive Sliding Mode Control of Uncertain High-Order Nonholonomic Systems with Unknown Control Coefficients

Abstract EN

This paper investigates the global stabilization problem for a class of high-order nonholonomic systems with unknown control coefficients and uncertain nonlinearities.

An adaptive sliding mode control (SMC) law based on a constructive manipulation is proposed by adding a power integrator technique.

A switching control strategy is employed in the control scheme to overcome the uncontrollability problem associated with the nonholonomic systems.

The designed sliding mode controller could guarantee the attractiveness of the sliding surface S=0 and achieve the asymptotical convergence of the state as well as the boundedness of the estimated parameters.

A simulation example is provided to demonstrate the effectiveness of the proposed scheme.
