[0151] The wind turbine fault-tolerant control method based on robust self-adaptive and sliding mode variable structure control proposed by the present invention is described in detail in conjunction with the accompanying drawings and specific implementation methods as follows:
[0152] 1. A fault-tolerant control method for wind turbines based on robust adaptive and sliding mode variable structure control, which is characterized in that the method uses robust adaptive control and sliding mode variable structure control to strongly stabilize the fault system, and the control method refers to variational gradient The idea of the descending algorithm is to adjust only one variable at a time to achieve the purpose of stable fault tolerance; to design corresponding fault-tolerant controllers for two different faults. When the system fails, the active fault-tolerant system will provide real-time information according to the fault diagnosis mechanism. Select and switch the correspo...
