Finite-time event-triggered control for stochastic systems with multiple disturbances

Abstract

This article aims to investigate the finite-time event-triggered anti-disturbance control problem for stochastic systems subject to multiple disturbances, and the disturbances include exogenous disturbance, norm-bounded disturbance and white noises. The stochastic disturbance observer is devised to estimate the exogenous disturbance, then the finite-time event-triggered anti-disturbance control scheme is proposed by combining finite-time control with event-triggered control, which ensures that the composite system is stochastic finite-time boundedness and stochastic finite-time stable under different conditions. Finally, the feasibility and availability of the proposed finite-time event-triggered anti-disturbance control scheme are verified by two simulation examples.
