摘要：An event-triggered based on prescribed performance control (PPC) for the tracking control problem of strictfeedback uncertain nonlinear systems with input saturation constraint is studied. First, a smooth nonlinear function is introduced to approximate the saturation function. Secondly, the PPC design process of a class of uncertain nonlinear systems and a new error transformation function are designed to guarantee the output of the system does not violate the set constraints of the preset functions. Thirdly, an eventtriggered based on adaptive PPC for a class of uncertain nonlinear systems is implemented. It makes all closed-loop signals in the system uniformly ultimately bounded (UUB). Finally, an example is given to demonstrate the effectiveness of the proposed method.
