摘要: 设计了适用于小转矩范围的电动式负载模拟器,并分析了其结构和动态性能. 介绍了电动式负载模拟器的结构和工作原理,建立了电动式负载模拟器的数学模型,并对系统稳定性进行了理论分析和仿真研究.在系统中引入多重反馈和前馈,再辅以控制方法进行电机控制,收到了良好的效果.仿真数据表明,所设计的电动式负载模拟器在小转矩范围内能够达到电液负载模拟器的控制性能指标.

Abstract: Motor-drive load simulator with small torque outputs was designed, its stability and dynamic performance were analyzed. Based on an introduction to the structure and principle of electrical loading system, a mathematical model of the system was put forward to analyze and to simulate its stability and anti-jamming. By including multi-feedback and feedforward in the system and using control methods to control DC-motor, improved performance of the system was obtained. Simulation results indicated that the performance of the motor-drive load simulator is as good as that of the electro-hydraulic load simulator in the range of small torque.
