It described a control method of induction motor for high-power ship propulsion, analyzed its principle and implementation of indirect stator-quantities control（ISC） and proposed an improved speed-sensorless identification algorithm based on MARS. Results of ground experiment and field operating verification show that using this algorithms, torque output error and harmonic current content of motor are less in the whole speed range under the rated torque operating condition; high dynamic acceleration requirements can be achieved in the power restrictions and other harsh operating conditions; the inverter system can fully meet the high-performance requirements for ship-propulsion applications.
