Multivariable Centralized Control with Decoupling and Feedforward Compensation for Residential Wind Turbine

The small wind turbines for residential uses are multivariable processes that work under turbulent wind conditions and abrupt electrical load changes. In these processes, it is necessary to apply a complex control system that allows a good performance on the power production. For this aim, in this paper, a multivariable centralized control by decoupling is presented to control the wind turbine, in comparison with a decentralized control. The problems due to disturbances by wind turbulences and electrical load changes are reduced using feedforward compensation.
