Real-Time Speed Control of a PMSM for Wind Turbine Application

This paper presents the real-time speed control of permanent magnet synchronous machine (PMSM) in a motoring mode for variable speed wind energy conversion system application. For this purpose, a discrete real-time laboratory test-rig is prepared using Permanent magnet synchronous servo motor, GUASCH Inverter and Texas instrument TMS320F28069 Digital Signal Processor (DSP) discrete real time microcontroller control card in a GUASCH board for implementing the designed PI current controller and PI speed controller. In addition, a simulation model of the system is prepared in MATLAB Simulink user-defined function blocks considering the dynamic mathematical equations of every part in the system. Finally, the achieved results of test-rig show that the system works very well for different transient speed changes. Moreover, it shows that the real-time time results validate the MATLAB simulation model results of the system.
