Abstract:

A parallel control-based event-driven approximate optimal control method was proposed for discrete-time nonlinear systems.Firstly, based on the time-triggered optimal value function and optimal control law, a novel triggering condition was developed and the asymptotic stability of the closed-loop system was proved based on the Lyapunov method.Secondly, a parallel control method using neural networks and adaptive dynamic programming techniques was proposed to predict the next state of the system and to obtain the optimal value function and control law.Finally, the effectiveness of the developed method was validated by numerical examples.

Key words: event-driven control, nonlinear optimal control, parallel control, adaptive dynamic programming
