| 英文摘要 |
| Aiming at the abrupt faults of variable pitch actuator of wind turbine, an adaptive state feedback sliding mode
fault-tolerant control (AFSMFTC) strategy based on wind speed estimation is proposed in this paper. Firstly, an active robust
fault-tolerant controller based on adaptive state feedback sliding mode control is designed, and the control law is designed
with full order compensator. Then, the combined radial basis function neural network (CRBFNN) based on variable speed
grey wolf optimization (VGWO) algorithm is used to estimate the wind speed, which can improve the reliability of the
control system and the accuracy of wind speed measurement. Finally, the stability of the controller is discussed based on
linear matrix inequality (LMI) and Lyapunov theory. The simulation results show that the proposed fault-tolerant control
method can achieve better control effect under the condition of healthy and faulty actuators. |
