Simulation on Starting Performance of a Linear Engine/Generator

摘要:

对一台直线发动/发电机的起动过程进行了研究，提出了基于速度信号的起动力方向控制模式，并通过Matlab/ Simulink动力学仿真研究了该模式下系统的运行特性及起动性能。结果表明：起动力的精确换向是直线发动/发电机起动控制的关键；在基于速度信号的起动力方向控制模式下，系统的能量损耗较小，经优化的系统起动力约为135N；运动组件在起动过程中作频率、幅值逐渐增大的直线往复运动。

Abstract:

Driving force direction control strategy based on velocity signal for a linear engine/generator system was proposed and starting performance of this system was studied with Matlab/Simulink software. Results show that driving force direction needs be precisely controlled for starting successfully. With the control strategy based on velocity signal, system power loss is little and the driving force is optimized at 135N. Furthermore, the working frequency and distance of the moving part increases gradually for a few starting cycles until it reaches the steady state condition.
