Observer-based spatiotemporal event-triggered fuzzy resilient control for temperature profile of high-speed spacecraft

Abstract

This article proposes an observer-based spatiotemporal event-triggered fuzzy resilient controller design method for the temperature profile across the fin of high-speed spacecraft. Initially, the considered nonlinear system is reconstructed via the Takagi–Sugeno fuzzy rule. Then, to simultaneously realize the observation and control of the spacecraft surface temperature, an observer-based point controller is proposed in terms of averaged measurements. In addition, taking the network congestion issue into consideration, a spatiotemporal event-triggered mechanism and a quantization method are adopted to reduce data transmission and enhance bandwidth utilization. Furthermore, to resist cyberattacks and actuator faults, a fuzzy resilient control strategy is designed to ensure the stability of the closed-loop system with $$ disturbance attenuation performance. Finally, simulation results for a cooling fin are presented to demonstrate the validity of the proposed method.
