摘要
阐述了流量放大器的工作原理，建立了流量放大器的静动态数学模型，并利用计算机进行数字仿真。该仿真程序不仅适用于线性定常系统，也适用于具有死区、饱和非线性和时变系统的动态仿真，最后对流量放大器的稳定性和动态响应时间等动态指标作了分析，并得出结论。
The principle behind the flow amplifier is described and the static and dynamic mathematical models is established.On this basis,digital simulation is implemented on a computer.The simulation program fits not only linear con-stant system,but also the nonlinear dynamic system with dead area and unsaturation varying with time.The ability and response time,etc of dynamic performance of the flow amplifier are analysed.Finally,the dynamic indexes of the flow amplifier are analysed and some improtant conclusions are drawn.
