摘要：
A new chattering-free variable trending law for discrete-time sliding mode control is designed. On account of actual controller of inertial system where the velocity of output is limited, the function of varying speed of trending law is introduced. A novel idea is firstly presented that through designing the acceleration of trending law the expected trending law is constructed to make the controller's physical meaning distinct, and the design of controller more flexible and easier. As to the nominal system, the trending law can make the value of switch function reach zero in finite time without chattering. For uncertain system satisfying matching condition, this trending law can make the value of switch function monotonously reach a certain value, which is related with external disturbance and can be arbitrarily small by designing the parameter of controller. © 2013 Acta Automatica sinica.
