Abstract

Cable winch is a crucial component of the shore power system, and Permanent Magnet Synchronous Motor (PMSM) with high efficiency and good maintainability is always used as the drive motor for ship cable winch. In order to deal with the various and complex ocean environment, it is rather important for cable winches to keep the tension constant when picking and laying cables so as to realize constant torque control. According to the particularity of cable winch load which includes time variant, sudden change, and non-linearity, the combination of self-adapting fuzzy PID controller and direct torque control (DTC) strategy modulated by space vector is presented in this thesis to realize the control. Meanwhile, Matlab/Simulink is used to verify this control strategy. The result indicates that a drive motor controlled by SVM-DTC control strategy based on self-adapting fuzzy PID control can not only maintain the advantages of direct torque control well, but also present excellent dynamic and static characteristics at the same time, which would effectively reduce electromagnetic torque and flux linkage ripple. Therefore it is quite adapTable for the cable winch drive system.
