摘要：
This paper presents a nonlinear control structure for variable-speed squirrel cage induction generator-based wind energy conversion systems. The proposed control structure consists of two control systems designed for machine side converter (MSC) and grid side converter (GSC). The MSC controller is based on adaptive input–output feedback linearization designed in a new reference frame and is responsible for controlling the flux and torque of the machine. Torque control is achieved through a PI controller that its output determines the speed of the presented reference frame at each moment. For the GSC, a sliding mode-based control system is designed to control the DC link voltage in addition to controlling the active and reactive power exchanged with the grid. The validity and effectiveness of the proposed control structure have been investigated through simulation studies in MATLAB® software environment.
