船舶电力推进直接转矩与转速复合控制

Hybrid control of direct torque and speed for marine electrical propulsion

针对常规船舶电力推进控制器没有充分利用推进系统的动态特性这一问题,提出了包含速度、转矩、推力和功率特性的复合控制算法,建立了基于SIMOTION的船舶电力推进模拟设备,进行推进电机复合控制的试验研究.分析并比较了速度、转矩与功率3种控制策略.试验结果表明:利用直接转矩与转速复合控制,能获得精确和平滑的转速与转矩控制,最小的转速与转矩脉动,以致最小的机械磨损.

The conventional marine electrical propulsion controller does not fully utilize the dynamic characteristics of the electrical propulsion system.This paper presents hybrid control algorithms which include the capabilities of speed,torque,thruster,and power,and establish the simulation device of marine electrical propulsion based on SIMOTION.Additionally,experimental study of hybrid control for propulsion motors was performed.Comparison study and analysis of propulsion motor speed,torque,and power controllers was achieved.The experimental results show that hybrid control strategies can obtain accurate and smooth speed and torque control as well as lower fluctuations and mechanical wear.
