Adaptive control of wind PMSG

The paper suggests an adaptive control of the wind permanent magnet synchronous generator (PMSG) driven by a variable speed wind turbine. Processes in wind generator have been studied using a mathematical model. The results show suitability of using adaptive control using Optimal Singular Adaptive (OSA) observer. A basic distinctive feature of OSA observer is the simultaneous estimation of the initial state vector, which is used for optimization of unknown current state vector estimation, and estimation of other parameters. Besides that, iterative identification methods for unknown parameters and state vector estimation are not used, but a direct method of solving linear systems of algebraic equations, accelerating the control process and improving the control quality is used.
