摘要：

In this paper, a nested saturated second-order sliding mode (SOSM) controller has been constructed based on the saturation technique and geometric method. The proposed controller includes a saturation function, which could change the phase trajectory of the sliding variables under the traditional SOSM algorithms. The geometric method has been used to test the finite-time convergence of the sliding variables and reveal the relations between the control parameters and the shape of the phase trajectory. Finally, a numerical example has been given to validate the effectiveness and feasibility of the proposed method.
