Dual-channel event-triggered data-driven control for energy storage system with input saturation and packet loss

This paper proposes a dual-channel dynamic event-triggered (DET) constrained control strategy with packet loss compensation to regulate power in battery energy storage systems (BESSs) under packet loss conditions and input saturation constraints. The compact form dynamic linearization (CFDL) method is first employed to simplify the modeling of BESSs. Based on the linearized model, output data packet loss is compensated, while an input data packet loss compensation mechanism is developed using the latest control increment. A dynamic antiwindup compensator is designed to mitigate the effects of constraints on the magnitude and rate of control input. Furthermore, semi-independent DET mechanisms are established for control input and measurement output channels to reduce communication and computation resource consumption. Theoretical convergence analysis is given by employing the contraction mapping principle and indicates that the tracking error is uniformly bounded. Finally, numerical simulations verify the efficacy of the proposed approach.
