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

if nargin && ischar(varargin{1}
gui_State.gui_Callback = str2func(varargin{1};
% hObject handle to pushbutton1 (see GCBO

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

% applied to the GUI before Liushuai20122510_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Liushuai20122510_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton".
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
% singleton*.
%
% H = LIUSHUAI20122510 returns the handle to a new LIUSHUAI20122510 or the handle to
% the exwenku.baidu.comsting singleton*.

最后,点击“退出”结束程序
四、附录
代码:
function varargout = Liushuai20122510(varargin
% LIUSHUAI20122510 MATLAB code for Liushuai20122510.fig
% LIUSHUAI20122510, by itself, creates a new LIUSHUAI20122510 or raises the existing
用Matlab创建用户界面,并完成以下功能
a将产生未综合系统的根轨迹图以及0.707阻尼比线,你可以交互地选择交点的运行点。界面能显示运行点的坐标、增益值以及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稳态误差
b显示未综合系统的阶跃响应
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
