In recent years. wind energy becomes one of the most important sources for electricity production. For instance it is predicted that the installed wind capacity in China will be about 40 GW till 2020. The permanent magnet synchronous generators (PMSG) which contains of a permanent magnet that causes DC excitation current in the windings. are widely used in wind turbines. The advantage of this type of generators in comparison to the others. are higher efficiency. controllable terminal voltage and reactive power. It is also noticeable that the PMSG speed can be controlled by the converter which leads to MPPT implementation. The MPPT is always implemented to control the generator speed and output power between the cut-in and nominal wind speed. It is necessary to control the generator speed by pitch or stall control for upper rated wind speeds. In this paper after explaining the structure and components of a typical wind turbine with permanent magnet synchronous generator. designing of an offline DMC (Dynamic Matrix Control) and a gain scheduled PI pitch controller are presented. Both of these controllers have been tested on the practical simulator of 100 KW wind turbine with PMSG generator and the results are presented and compared.
