摘要
对一台直线发动/发电机的启动过程进行了研究,提出了基于速度信号的启动力方向控制模式,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启动性能.结果表明,启动力的精确换向是直线发动/发电机启动控制的关键;在基于速度信号的启动力方向控制模式下,系统的能量损耗较小,经优化的系统启动力约为135N;运动组件在启动过程中作频率、幅值逐渐增大的直线往复运动.
Driving force direction control strategy based on velocity signal for a linear engine/generator system was proposed and the starting performance of this system was studied with Matlab/Simulink software. Results show that the driving force direction needs to be precisely controlled for a successful start. With the control strategy based on velocity signal, system power loss is little and the driving force is optimized at 135 N or so. Furthermore, the working frequency and distance of the moving part increases gradually for a few starting cycles until it reaches a steady state condition.
