Vectorial command of an asynchronous motor supplied by a photovoltaic generator

In the setting of its politics to promote renewable energy, Tunisia developed a large program on exploitation of photovoltaic systems essentially to provide rural electrification needs. These needs increases continually following-up the amelioration of the life level of citizens. These citizens needs involved from lighting and media communication (radio, TV) to needs exploiting motors: refrigeration and pumping. In fact the fluctuation of solar energy one hand and the necessity of optimizing available solar energy on the other, it becomes useful to develop new efficient and flexible modes to control motors. We present in this paper the vectorial control of an asynchronous motor supplied by a photovoltaic system.
