In this paper, an intelligent speed controller of permanent magnet synchronous motor is investigated. The motor speed leads a photovoltaic water pumping system. The photovoltaic generator is connected to chopper converter that is controlled by technical fuzzy logic with a view to aperate can be tracked the maximum power point whatever the temperature and solar irradiance variation. Thus, to analyze the performance of speed control between the proportional integrator controller and fuzzy logic
