Decoupling Adaptive Sliding Mode Observer Design for Wind Turbines Subject to Simultaneous Faults in Sensors and Actuators

This paper proposes an adaptive sliding mode observer (ASMO)-based approach for wind turbines subject to simultaneous faults in sensors and actuators. The proposed enables the detection of actuator sensor without need any redundant hardware components. Additionally, speed variations are considered as unknown disturbances, thus eliminating accurate measurement or estimation. ASMO estimation reconstruction descriptor states disturbances. design implements principle separation enable use nominal controller during faulty conditions. Fault tolerance is achieved by implementing a signal correction scheme recover behavior. performance validated using 4.8 MW turbine benchmark model various faults. Monte-Carlo analysis also carried out further evaluate reliability robustness presence errors. Simplicity, ease implementation decoupling property among positive features approach.
