Computer use of vertical feed system for open-loop control. 利用微机对纵进给系统进行开环控制。
The function is introduced that after system parameter is input to computer, the open-loop amplitude phase frequency characteristic curve can rapidly be displayed and printed, the phase angle margin and gain margin are calculated simultaneously and the method of close-loop control system stability is deduced. 介绍了利用计算机在输入系统参数后,能迅速显示和打印出开环幅相频率特性曲线,同时计算相位裕量和增益裕量及判定闭环控制系统稳定性的方法。
