• This work has grown out of studies by Kamzin Technology (now GEC) on behalf of Windlite.
• It was also influenced by studies of the mechanics of teetering rotors.
• The forces from the tail vane and from the eccentricity of the thrust are not the only forces affecting the yawed equilibrium.
• the subsequent slides discuss the relevant aerodynamic forces on the yawed rotor.

In this paper, an adaptive control is proposed to maximize the energy conversion for a wind turbine driven by a PWM (Pulse Width Modulation) Inverter. This paper focuses on the optimization of the current loops of the  machine. Two different strategies of wind turbine management have been tested in steady and transient state (with the variation of the load). The principle of the optimization consists of minimizing Joule losses in PWM and Generator. The second strategy (adaptive) is implemented with successful results.
