High-Order Sliding Mode Design Based on Geometric Homogeneity and Fast Terminal Sliding Mode
Authors: , ,
Abstract: A high-order sliding mode control algorithm is proposed for nonlinear uncertain systems based on geometric homogeneity and fast terminal sliding mode. Homogeneity approach used to stabilize the nominal system, and fast terminal sliding mode used to reject the uncertainty, are applied to constructing the controller. High-order sliding mode is established by the proposed algorithm, the boundary of the uncertainty is not required, and the global robustness is achieved. Additionally, the resulting control law is continuous, which is beneficial to reduce the chattering effect. Simulation results of the proposed algorithm confirm the effectiveness.
