In this paper, an optimized event triggering scheme and an LQG controller design is proposed for a linearized wind turbine model in a microgrid system. The system is modeled as an event triggered system based on asynchronous-sampled data system (ASDS) approach. Networked induced delays are considered in the communication channel. Particle Swarm Optimization (PSO) is employed to optimize control and communication cost, while reducing the event rate. Simulation results are included to elucidate the proposed controller design. A comparative analysis is also presented to demonstrate the significance of optimization in event sampling. [ABSTRACT FROM AUTHOR]
