Robust performance of self-scheduled LPV control of doubly-fed induction generator in wind energy conversion systems

This presentation describes a new current control design for doubly-fed induction generators in wind turbine systems. The design is based on the linear parameter varying (LPV) systems approach. Robust performance for the closed-loop system is achieved based on the design. Furthermore, robust performance of the controlled LPV system with respect to other machine parameter variations and the impact of a stator voltage dip are investigated. They show that a large performance improvement can be achieved in comparison to more classical controller designs.
