| Abstract: | Aiming at the sensor fault of multi-variable nonlinear system,a novel fault tolerant control(FTC) method based on neural network models is investigated.The method colligates weighting moving average residual within L time window to detect multi-type sensor fault,and uses neural network technique to online re-construct sensor signal,and achieves the tolerant proportional integral derivative(PID) control.The three-tank with multiple sensor fault concurrence is simulated,the simulation result shows that the fault detection and tolerant control strategy proposed have stronger robustness and tolerant fault ability. |
