负载转矩观测器在船舶推进系统中的应用

Application of load torque observer in ship propulsion system

近年来,交流电机逐渐被应用于船舶推进系统中,由于受到海洋环境复杂性的影响,电机负载容易产生突变,如何提高船舶推进系统抗扰动能力成为人们研究的重点。本文研究船舶推进系统和滑模控制理论,在此基础上,利用负载转矩观测器的实时监测数据对船舶推进系统进行动态控制,降低负载扰动影响,提高系统的稳定性和安全性。

In recent years, the AC motor is applied in ship propulsion system. Due to the complexity of the marine environment, motor load is prone to mutation. How to improve the anti-disturbance ability of the system becomes the focus of the study of ship propulsion. This paper studies the ship propulsion system and sliding mode control theory, based on the dynamic control of the ship propulsion system using the real-time monitoring data of the load torque observer, reduces the effect of the load disturbance, improve the system stability and security.
