prony's method is used in open-loop transfer function identification and computation of residues 把prony方法用于不含控制器的系统开环传递函数辨识,以及留数的求取。
based on the compensated open-loop transfer function, the system stability at the small-signal perturbation and the system response to step signal are analyzed 根据加入补偿网络后的开环传递函数,分析了系统在小信号扰动时的稳定情况及系统对阶跃信号的跟踪能力。
