Optimal event-triggered control of uncertain linear networked control systems: A co-design approach. Sahoo, A., Narayanan, V., & Jagannathan, S. In 2017 IEEE Symposium Series on Computational Intelligence, SSCI 2017 - Proceedings, volume 2018-Janua, 2018. abstract bibtex © 2017 IEEE. In this paper, a co-design approach for event-based optimal state regulation of an uncertain linear networked control system is presented. Both the transmission intervals and the control policy are optimized by introducing a novel performance index such that the error in the control policy due to event-based transmission can be maximized. The event-triggering mechanism uses the worst case control input error as threshold to decide the optimal transmission instants. Stochastic Q-learning approach is used to design both the control policy and event-triggering condition without explicit knowledge of the system dynamics. The event-based Q-function parameters are updated using a hybrid scheme both at triggering instants and during inter-event times to accelerate the parameter convergence. The asymptotic stability in the mean square of the closed-loop system is demonstrated using Lyapunov analysis with the assumptions of persistence of excitation of regression vector. Finally, numerical results are included to substantiate the analytical design.
