Regional pole placement of a Markovian jump model for wind turbine generator system

Abstract

This paper discusses the regional pole placement problem for Markovian jump system, and the corresponding application on wind turbine generator system (WTGS). Through sampling the low-frequency wind speed datas into separate intervals, the dynamic process of WTGS can be modelled into Markovian jump system. The traditional operating points of wind turbine are divided into separate subregions correspondingly, where the model parameters and the control mode can be fixed in each mode. However, the control designed for each operating subregion can not guarantee the whole dynamic response performance of WTGS, which is caused by the stochastic switchings between different system modes. Hence, the pole placement problem is discussed for linear Markovian jump systems, and applied on improving the dynamics response of WTGS.
