Abstract

This paper presents modelling and simulation of a wind turbine driving a grid connected induction generator. A DC motor is used to emulate the performance of the wind turbine. Different parts of the system have been modelled using MatLab - Simulink. A model of a DC motor derived by a converter is employed to emulate the performance of the wind system. A speed control loop is used to force the dc motor shaft to follow the induction generator shaft which is coupled to the wind turbine.

Keywords

Abstract

According to various advantages of linear induction motor (LIM), such as high starting thrust force, high speed operation and reduction of mechanical losses, more applications have utilized this type of motors. Direct Thrust Control (DTC) technique is considered as one of the most efficient techniques that can be used for LIM. DTC is preferable to give a fast and good dynamic thrust response. So, to improve the accuracy and robustness of contouring control for CNC machine tools, linear induction motors with a direct thrust control technique are introduced for driving these machines. An industry standard motion control system is applied for reducing the tracking error and improving the desired accuracy. Different loading conditions are simulated to validate the reliability and robustness of the introduced system to match the application field. The proposed system is simulated using the MATLAB/SIMULINK Package; simulation results validated both tracking accuracy and robustness of the proposed motion control system for contouring control for a CNC (Computer Numerical Control) milling machine.
