Observer-based robust fault-tolerant control for wind energy system

Wind energy capacity has been expanding globally. Most wind turbines are in hostile environments, requiring fault-tolerant control approaches. This project aims in providing a robust, fault-tolerant wind energy control system. A robust measure determines the sensor's stability and performance-vulnerable flaws following likely the failures. The suggested approach assures the highest possible performance in the case of a sensor failure and irregular operating conditions. Flawed generator speed sensors reduce the wind energy control system's performance and safety margin which maintains the system efficiency. This paper presents an observer-based fault-tolerant generator speed sensor control system. It's a passive fault-tolerant control system with no controller reconfiguration. Instead of sensor output, the controller receives anticipated generator speed. The mathematical model is used to build a fault-tolerant observer that accounts for wind turbine gearbox and bearing problems. Simulation results prove the method's viability.
