This paper presents an analysis by which the dynamic performances of a permanent magnet brushless DC (PMBLDC) motor is controlled through a hysteresis current loop and an outer speed loop with different controllers. The dynamics of the photovoltaic pumping drive system with sliding mode speed controllers are presented. The proposed structure is comprised of a photovoltaic generator associated to a DC-DC converter controlled by fuzzy logic to ensure maximum power point tracking. The PWM signals are generated by the interaction of the motor speed closed-loop system and the current hysteresis. The motor reference current is compared with the motor speed feedback signal. The considered model has been implemented in the Matlab /Simpower environment. The results show the effectiveness of the proposed method in increasing the performance of the water pumping system.
