三、已知某前向通路的传递函数(如图所示)12.010)(+=s s G今欲采用负反馈的办法将阶跃响应的调节时间s t 减小为原来的0.1倍，并保证总放大系数不变。

试选择H K 和0K 的值。

（10分）解：原系统的放大系数为10，调节时间为0.6（5%∆=±）。

采用负反馈后由系统的结构框图可得系统闭环传递函数为：()()()00101100.211110HH HK G s K K s s K G s K φ+==+++系统的调节时间减小为原来的0.1倍，可得：0.20.02110HsK =+放大倍数保持不变，可得：1010110HK K =+求解上两式可得：0.9H K =，010K =。

四、简化下面系统方框图，并求系统传递函数。

（要求：须有简化步骤）（10分）解：根据方框图移动法则可得：进一步化简：计算可得系统的闭环传递函数为：1231412123242123141G G G G G G G H G G H G H G G G G G ++++++。

五、图示为由一RC 组成的四端无源网络。

试列写以U1（t ）为输入量，U2(t)为输出量的网络微分方程。

（15分）解：假设流过电容1C 的电流为1i ，流过电容2C 的电流为2i ，根据基尔霍夫定律可得：()1121111R i i i dt u C ++=⎰2221u i dt C =⎰12221211i dt R i i dt C C =+⎰⎰对上列三式两边取微分并化简可得：()11222111222221R C R C u R C R C R C u u u ++++=六、设单位反馈控制系统开环传递函数如下，试概略绘出系统根轨迹图（要求确定分离点坐标d ，渐近线，与虚轴交点）。

（15分）)15.0)(12.0()(++=s s s Ks G解：将系统的开环传递函数写为零极点形式可得：()()()1052KG s s s s =++系统为3阶，所以根轨迹分支数为3条。
