【Abstract】 Sensor control of ship motor is the key technology to ensure the stable power output of ship motor, motor control is easily affected by the electromagnetic coupling interference caused no small disturbance, high control precision,proposed sensorless control method based on sliding mode observer motor ship, mining for ship output current, with sliding mode observer voltage, power and other parameters of the original collection the control of the original information processing from the town of qualitative acquisition of motor output, the equivalent circuit model of ship motor design, current and voltage structure of motor sensorless controller changing circuit, using sliding mode inversion integral control method of error compensation, improve the precision of motor output modulation parameters, realize the sensorless control of ship motor. Test results show that using the method of ship motor without position sensor output can better control, the motor output voltage stability, power factor can be greatly improved, improved ship motor operating stability.更多还原
