Online real-time control of hydroturbine regulation system fault with state time lag

Mechanical faults, time-varying faults and other disturbances in the role of multiple coupling, the stable operation of the hydroturbine regulation system has caused great obstacles. This study concentrated on the output feedback fault-tolerant (FFT) control technology and T-S state feedback predictive control technology using the actual operating conditions of the numerical simulation test. The results show that the control technique has good identification tracking and control effect, and can make the system stabilize within 2 s in the case of disturbance. This shows that the control system designed by the research institute has good applicability and provides data reference for the intelligent control operation and maintenance of the hydroturbine regulation system.
