自动控制原理Matlab程序作业（精）

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,点击“退出”结束程序 四、附录 代码:
