Abstract :
Warship electrical power propulsion system is researched, multi-phase permanent magnet synchronous motor propulsion control system has expectant optimal dynamic performance under appointed condition, through modeling of screw propeller load application of inverse system methods of nonlinear system and optimization design of controller parameters, based on the mathematic model and nonlinear characteristics of electrical power propulsion system. The uncertainty of parameters can worsen feedback linearization effect of system, not achieving expectant optimal performance, even make system unstable. The extent Kalman filter is adopted to estimate system parameters, satisfied effect is acquired
