Protocol-based control for wind turbine generator with semi-Markov

This paper is concerned with the protocol-based control design problem for wind turbine generator systems (WTGSs) via a proportional-integral observer. Considering the variable actual wind speed, the operation points of WTGSs between different subareas are described by a semi-Markov jump process. To efficiently modulate transmission frequency, an adaptive-memory event-triggered protocol (AMETP) is constructed using a sequence of previously broadcasted packets and adaptive triggering thresholds, resulting in better dynamic performance. Benefitting from the parameter-dependent Lyapunov stable theory, some sufficient criteria are formulated for the stochastic stability of the closed-loop systems. At last, the feasibility of the presented approach is tested via a numerical example. (c) 2023 The Franklin Institute. Published by Elsevier Inc. All rights reserved.

Automated summary

This paper focuses on the control design problem for wind turbine generator systems (WTGSs) using a proportional-integral observer. A semi-Markov jump process is used to describe the operation points of WTGSs between different subareas considering variable wind speed. An adaptive-memory event-triggered protocol (AMETP) is constructed for efficient transmission frequency modulation, resulting in improved dynamic performance. Sufficient criteria for the stochastic stability of the closed-loop systems are formulated based on parameter-dependent Lyapunov stability theory. The feasibility of the approach is demonstrated through a numerical example.
