marine engineering ship electrical propulsion system fault-tolerant compensation control permanent magnet synchronous motor unchangeable principle of magnetomotive force open-circuit fault
Based on the fault-tolerant compensation control strategy of the unchangeable principle of magnetomotive force(MMF), the mathematical model of the MMF under healthy condition was studied in the permanent magnet synchronous motor(PMSM)applied in ship electric propulsion system, and the mathematical model of the MMF under one-phase open-circuit faulty condition was established. When one-phase open-circuit fault occurred, the MMF could be remained unchanged by changing the size and angle of currents in two other healthy phases. And the vector control based on space vector pulse width modulation(SVPWM)was still applicable in the motor control. The whole simulation model of ship electrical propulsion system was set up and simulated in MATLAB/Simulink combining the system model of ship electrical propulsion system, and the parameters of torque, speed and current were analyzed. Simulation result shows that the ripple of output torque in the propeller model, and the motor’s torque, current and speed ripples are 0.85%, 5.90%, 6.25% and 2.01% respectively, which shows that the motor has good operating performance under healthy condition. Under one-phase open-circuit faulty condition, the failure response of the propeller without fault-tolerant compensation control strategy is intense, the ripple of output torque in the propeller is 22.2%, the output torque, current and speed of the propulsion motor have large fluctuations that are about 82%, 50% and 33% respectively, and the flux linkage track motor’s stator is unstably elliptical. After using the vector fault-tolerant compensation control strategy based on the unchangeable principle of MMF, the output torque of the propeller will return to the stable value and the ripple is 1.02%. The ripples of output torque, current and speed of the motor are significantly decline that are about 6.20%, 6.78% and 2.22% respectively. The ripples limits are close to the values under healthy condition, and the flux linkage track of motor’s stator returns to be the same circle under healthy condition. So the propulsion motor can run normally under healthy and open-circuit faulty conditions when the fault-tolerant compensation control strategy is adopted, and the propeller load and the propulsion motor performance can match well all the time. 2 tabs, 9 figs, 26 refs.
