An event-based multi-inverter system constraint adaptive critic control method

Abstract

The application introduces feedforward control, asymmetric constraint feedback control and event triggering mechanism, and proposes a constraint adaptive critic control method for multi-inverter system based on events. In the implementation of multi-inverter consistency control, the traditional adaptive critic control (ACC) algorithm has high requirements for system model selection when tracking the leader trajectory, and the communication efficiency is low, which may lead to the decline of control performance. First, the feedforward control is introduced to ensure accurate tracking of the system. Second, a suitable non-quadratic function is introduced into the cost function of each follower agent to achieve asymmetric constraints on control input. In addition, due to frequent communication between multiple agents, resource waste will be more serious. Therefore, a distributed event triggering mechanism is introduced to save communication resources and improve control efficiency. Finally, the effectiveness of the algorithm of the application is verified by using a multi-inverter system.
