Dynamic Memory Event-Triggered Predefined-Time Control for Stochastic Nonlinear Time-Delay Systems With Unknown Input Hysteresis

This paper proposes a novel dynamic memory event-triggered predefined-time control method for stochastic nonlinear time-delay systems with unknown input hysteresis. Different from existing results, this study focuses on the predefined-time stability of stochastic nonlinear systems. In the design of the predefined-time controller, command-filter technology is integrated, and the impact of filter errors on system performance is effectively mitigated. Considering the significant effect of historical data of unknown input Bouc-Wen hysteresis signals on current input signals, a dynamic memory event-triggered controller is proposed to enhance control accuracy. Simulations are conducted to validate the performance of the proposed control method.
