Neural quadratic sliding mode control of interconnected Markov jump systems through dynamic event-triggered observer

Abstract

This paper introduces an observer -based neural quadratic sliding mode control strategy for interconnected Markov jump systems faced with unknown interconnections, regardless of the high dimensionality of the systems. Firstly, a dynamic event -triggered scheme is constructed in the communication channel to the Lebesgue state observer, with which an integral quadratic sliding mode hyperplane is put forward; Secondly, a neural -based control method is put forward to make sure that predefined sliding hyperplane is attractive; In addition, the occurrence of Zeno phenomenon is also verified to be avoided with the implementation of the controller; Thirdly, linear matrix inequality technique and Lyapunov stochastic stability theory are proposed to check the stochastic stability of closed -loop systems, including sliding mode dynamics and error dynamics; Finally, simulation results on single -link robot arms are given to reveal the validity of the obtained results.
