摘要
针对螺旋桨负载模拟问题,提出电动负载模拟的实验方案。分析了电动负载模拟系统的结构、功能和控制策略,阐述四象限船桨建模方法,并应用硬件在环技术,进行基于硬件在环技术的螺旋桨负载模拟系统设计,研究结果表明该方法能够将船桨模型和关键硬件集成在一起。系统采用转速闭环和转矩开环相结合的控制策略,通过控制负载电机的电磁转矩来模拟螺旋桨负载特性,进行螺旋桨负载特性的半实物仿真实验,结果表明该方法是可行的。
Ror the propeller load emulation,an experimental scheme for electric load simulation was proposed based on analyzing the propeller load characteristics,whose structure,function and control strategy were analyzed in the paper,The modeling method of four-quadrant ship-propeller model was described,hardware in the loop simulation was adopted,the design of propeller load emulation system based on hardware in the loop was carried out,the key hardware of electric propulsion platform and ship-propeller model were integrated. A method which combines close loop speed control and open loop torque control was adopted. The load characteristics of the propeller were simulated by controlling the electromagnetic torque of the load motor,the semi-physical simulation experiment of the propeller load characteristics was carried out. The simulation experimental results show that the method is effectiveness.
