DESIGN OF A LINEAR SECOND ORDER CONTROLLER BASED ON A HIGH-ORDER OBSERVER TO ESTIMATE WIND SPEED IN WIND ENERGY CONVERSION SYSTEM

Abstract

In the wind energy converter control system, monitoring the maximum power operating point which is accomplished by varying the wind turbine speed is
a crucial responsibility. This calls for the measurement of wind speed and the transfer of wind speed data to the controller. This implies that in order to do this,
a large number of wind speed sensors must be used, but the outcomes do not ensure accuracy. As a result, individuals try to measure wind speed using various
techniques. A highly efficient control system will result from an accurate estimation of wind speed. Many prior observation sets that are not applicable to real
systems have been offered in order to estimate wind speeds matching to assumptions of slowly fluctuating aerodynamic moments. In order to precisely
determine the aerodynamic moment of the wind turbine and, consequently, the appropriate wind speed, this article suggests building a high-order turbulence
observer. Based on the findings of this observation, a high-performance optimum controller that maintains the ideal turbine speed is created.
