Abstract:
Podded thrusters,both can decrease the load and can improve the overall performance of ship,are the21’’` century developed new propulsion device. This paper mainly studies the propeller of the permanent magnet synchronous motor speed control problems,combined with SVPWM space vector pulse width modulation technology anddesign principle of the fuzzy PI controller, has a lot to improve in stability of motor speed control. SVPWM principlecan decrease the harmonic loss of motor, decrease the harmonic component of inverter output current and reduce pulsating torque;in addition its control is simple and easy digital realization,high voltage utilization ration. Fuzzy control can simplify the complex process of system design,and especially apply to nonlinear, time-varying and indetermination model system.
