Disturbance Attenuation of Uncertain Minimum Phase Nonlinear Systems via Adaptive Control
This paper focuses on the problem of disturbance attenuation for a class of single-input multioutput nonlinear systems. The system under consideration is cascaded by a zero-input asymptotical stable nonlinear subsystem and a triangle cascade subsystem with some uncertainties and disturbances. For the purpose to reduce the reservation which appears in robust control method, an adaptive controller based on Lyapunov theory and neural network algorithm is designed. It is proved that, when the disturbances appear in the system, this controller guarantees the L2-gain of the resultant closed-loop system from the disturbance input to the system output less than a given value. The simulation shows that the controller has small output and the closed-loop system has good performance.
