The main problem regarding wind power systems is the major discrepancy between the irregular character of the primary source (wind speed is a random, strongly non-stationary process) and the exigent demands regarding the electrical energy quality. This paper presents a feedback linearization controller based particle swarm optimization for maximum power point tracking of wind turbine equipped by PMSG connected to the grid, the proposed method which aims at maximizing the power captured by WECS. In order to drive the system to the optimal operating point using the selection of the controller pa- rameters with particle swarm optimization. The obtained simulation results with a vari- able wind profile show an adequate dynamic of the conversion system using the proposed approach.

Introduction
Wind energy has many advantages. Indeed, it is energy completely clean; it emits no waste or greenhouse gases. Its operation does not pollute the atmosphere or the soil or water and electricity that an abundant resource[1]. It is also one of power generation sources to achieve lower cost to the objec- tives [2]. Encourage the wind is essential because it is
renewable energy that the price of return is the cheapest for new developments[3]. The amount of energy recovered by the wind energy conversion systems with variable speed depends on the accuracy with which the search is made maximum power point tracking (MPPT) and also the type of generator unused. The energy conversion associated chains often use a synchronous generator with permanent magnets[4]. At pre- sent, Induction generators are widely used in wind energy conversion systems (WECS). The permanent magnet
