Nonlinear Controllers Based on Exact Feedback Linearization for Series-Compensated DFIG-Based Wind Parks to Mitigate Sub-Synchronous Control Interaction

The increasing penetration of wind power in the grid has driven the integration of wind farms with power systems that are series-compensated to enhance power transfer capability and dynamic stability.This may lead to sub-synchronous control interaction (SSCI) problems in series-compensated doubly-fed body oil induction generator (DFIG)-based wind f

Adaptive Model Output Following Control for a Networked Thermostat

The model of a networked temperature control system is easily affected by its surrounding environment.Because of that, it is hard to identify an accurate model.This paper proposes an adaptive model output following control based on system identification for a networked thermostat system.First, the time-varying system model is built via some thermal
