This paper presents the robust speed and parameters control of induction motors (IM) without speed sensors. The reactive power Model Reference Adaptive System was used to estimate the speed. The method is independent from stator resistance and pure integrator in reference model. Furthermore, parameters, used in the speed approximation, are not affected by temperature change. A squirrel-cage induction...
This paper presents a robust control design for a variable-speed adjustable-pitch wind turbine system. An adaptive decoupling controller is designed to drive the turbine speed to extract invariable power from the wind and to allow pitch adjustment to power regulation. An adaptive decoupling controller is designed to drive the turbine speed to extract maximum power from the wind and to allow pith adjustment...
