摘要
双闭环调速系统引入转速微分负反馈可以抑制和消除超调量,改善系统的动态性能。微分反馈的时间常数τ_(dn)取值不同,对系统的性能有很大影响。本文用对系统的数字仿真来分析τ_(dn)的取值及系统起动过程的性能问题。
The application of the speed differential negative feedback to speed regulation system with double closed loops could restrain or eliminate the overshoot and improve the dynamic performances of system. There will be a great influence upon the performance of system when the time constant τ_d_0 of the differential feedback gets different values. The writer of this paper analyses both the influence of the value of τ_d_0 and the performance problems of the system in starting process with the help of digital simulation methods.
