Efficiency Improvement of PM Synchronous Wind Generator Using Field Oriented Control with Model-base Current Observer

Abstract

One of the most applied and used control machine is vector control, which has the highest performance as well accurse results. The classic vector control is used the current sensor as the measure for generating current error. Though, by using sensor of current, an additional cost and a sophisticated system of control as well as channel noise are applied. The paper proposes a way out for Vector Control to eliminate current sensor. The approach solution is Field Oriented Control with Model-base Current Observer. This technique or method presents advantages compared to Classic vector control like simple system control, robust control, and decreasing the overall cost. In addition, the method offers during transient and steady state conditions stable and accurate performances for all machine applications. In this technique, estimating of currents generator is observed and fed to the vector control system. Moreover, this method provides robustness to parameter variations and good rejected for noise. The points of this method are demonstrated by simulating and testing the control system with the observer current. The method shows accurate and stable performance in both steady state and transient conditions. The method can be easily implemented in various generator control applications, including electric vehicles, robotics, and industrial automation.
