Sažetak
This research presents a novel fault-tolerant predictive power control method for a Doubly-fed
induction generator (DFIG) used in wind turbine control systems. Due to the proposed control
mechanism, the system can continue to function effectively despite open-circuit or short-circuit
faults in the insulated-gate bipolar transistors (IGBTs) of the MPC controller. Depending on the
type of problem and its location, the tolerant IGBT overcomes power oscillations and limits the
power converter’s potential switching states. By monitoring the optimal generator speed, wind
turbine control systems strive to maximize power output. For wind turbines operating in the
partial-load area, a fault-tolerant model predictive control strategy is recommended in order to
achieve control goals despite disturbances, uncertainties, sensor, and actuator difficulties. A high
order sliding mode observer (HOSMO) is used to evaluate both the actual states and sensor-faults
at the same time. A high order sliding mode (HOSM) control strategy based on the MPC controller is used to regulate the speed of wind turbines in order to harness the wind’s maximum
power.
