Abstract

This article focuses on the event-triggered control design for a class of p-normal switched stochastic nonlinear systems(SNS) with asymmetric output constraints. Firstly, in order to handle the pre-specified output constraints, a modified asymmetric tan-type common barrier Lyapunov function(CBLF) is put forward through the idea of piece-wise function. Combining the proposed CBLF with adding a power integrator technique, an event-triggered state-feedback controller is designed to ensure the switched SNS states asymptotically converge to zero in probability. Simultaneously, it is proved that the output will be constrained in the pre-specified bound and Zeno-behavior will not happen. Finally, a simulation of two-tank liquid-level system is given to indicate the effectiveness of the proposed method.
