1、c 输入控制器的参数, 绘制综合后系统的根轨迹图以及显示综合的设计点 （主导极点 , 允许不断改变控制器参数,知道所绘制的根轨迹通过设计点d 对于综合后的系统, 显示运行点的坐标、 增益,近似为二阶系统估算的超调量、调 整时间、峰值时间、阻尼比、无阻尼自然震荡频率以及误差系数e 显示综合后系统的阶跃响应二、运行结果 输入传递函数分子分母生成根轨迹图选择点并得到该点各项参数在下方输出面板输出获得阶跃响应图用 rltool（辅助,选择合适的插入零点输入零点,并得到根轨迹图选择根轨迹图上的任一点,得到数据,在下方输出面板输出得到阶跃响应图三、运行说明第一步, 在请输入分子后的输入框输入传递函数分子的

2、矩阵, 在下一输入框输入传递函 数分母并按“生成根轨迹图”按钮获得根轨迹第二步, 按选择点并显示各参数获得根轨迹图上任一点的各项数据, 数据全部输出在下 方输出面板第三步,按“生成阶跃响应图”按钮可以获得该函数的阶跃响应第四步,在“请输入插入零点”后的输入框中输入参数,并按“生成综合后根轨迹图” 按钮产生根轨迹 （可以通过点击 “根轨迹校正”按钮,调用工具箱拖动零点进行快速查看根 轨迹图,选择合适的根轨迹再在输入框中输入零点的值第五步,按“选择点并显示各参数（综合后系统 ”选取各点,查阅参数,数据输出在 下方输出面板上第六步,按“生成阶跃响应图（综合后系统 ”可以得到综合后系统的阶跃响应最后,
