摘　　要：为掌握线性压缩机的启动特性,以动圈式线性压缩机为例,建立了系统的运动方程,得到空载系统的开环与闭环传递函数,并运用Matlab软件进行空载系统的稳定性、时域和频域等特性的分析。结果表明,空载的动圈式线性压缩机总体上是稳定的,启动特性快,但是它的超调量过大,需要适当增加阻尼比以降低超调量。A moving coil linear compressor is taken for an example to find the linear compressors no-load characteristic. The open loop and closed loop transfer functions of the system in no-load condition are obtained derived from the equation of system motion. The Matlab software is applied to analyze the stability, time domain and frequency domain of the system. Result indicates that the moving coil linear compressor is almost stable at no-load stage, and the characteristic of staring is relative fast, but the overshoot is relative high, and the damping ratio should be increase to lower the overshoot.
