Experimental dSPACE analysis for permanent magnet synchronous generator used in voltage control

The synchronous machine with permanent magnets is a very interesting solution for the generation of electrical energy in isolated and autonomous wind turbine applications, but the stability of the voltage remains a major problem in its use. that's why we're proposing in this paper the analysis of a control scheme for keeping the RMS voltage output constant, the system is supplying by a permanent magnet synchronous generator (PMSG) with variable speed and load. A comparison is examined between experimental results using dSPACE board. the results are provided to verify the effectiveness of this approach and gives very high performance.
