变频装置及控制系统(Control system)：
It controls the speed of the motor,be divided into Cycloconverter and PWM. 推进电动机(Propulsion motors )： Synchronous motor,asynchronous motor.The trend is the permanent magnet motor.

Frequency Changer Drives And Control systems
The new pulse width modulation inverter device which the rectifier uses diodes,the inverter which uses IGBT,the filter is voltage-type has been used by more and more ships to promote the power.
Direct Torque Control technology originated in the 1980’s,in the 1990’s,Permanent magnet motor has already been used in direct torque control system.Nowadays,with the development and the introduction of the modern control theory and the intelligent control theory,there has appeared a lot of direct torque control systems as basic control theory with Fuzzy control theory, Neutral Network Control, Fuzzy Neutral Network Control,Nonlinear Control Theory and so on.Today,relative concentration research focus of both at home and abroad are:Used to reduce torque ripple voltage vector selection strategy;Stator flux compensation and stator resistance identification;Speed Identification;Speed control in low area,etc.
