Get AND Set • The two function are used to obtain or change Handle Graphics object properties. >> t = 0:0.1:4*pi; >> get ( h,’color’) >> y = exp(-t/5).*sin(t); >> get ( h ) >> h = plot(t,y); >> set ( h,’linewidth’,3) >> set ( h,’Marker’,’o’) >> set ( h,’MarkerSize’,20);
UICONTROLCreate user interface control • Matlab supports 10 unicontrol style. • Format : width / Length • uicontrol ( ‘style’,’oooo’,’position’,[x,y,w,l]); • oooo : push / slide / radio / frame /check / edit • uicontrol (‘style’,’list’,’position’,[200 320 80 30], ‘string’,’1|2|3|4’); • uicontrol (‘style’,’popup’,’position’,[200 370 80 30], ‘string’,’one|two|three|four’);
Type of Uicontrol Popup Push Slide Frame Check Radio Edit List
Create Figure Window & Axes • figure : Create Figure Window. figure('position',[20 20 700 500]); 產生新的視窗,其左下角之座標為[20,20] 長度為700,寬度為500 • axes : Create axes in arbitrary positions. • axes ('position', RECT) • RECT = [left, bottom, width, height](page477) • axes('position',[0.1 0.2 0.8 0.75]); • axis([-20 20 -20 20]);
Example - GUI Design clear; figH=figure('position',[20 20 700 500]); axes('position',[0.1 0.2 0.8 0.75]); axis([-15 15 -15 15]); pos1=[60,20,100,30]; h1=uicontrol('style','push','string','Simulation','position',pos1); set(h1,'callback','simulation'); pos2=[335,23,80,24];
Example - GUI Design h2=uicontrol('style','popupmenu','tag','UI9','string','Skew|Gradient|Chain|','position',pos2); pos3=[175,20,50,30]; h3=uicontrol('style','push','string','Clear','position',pos3); set(h3,'callback','mr_parking'); pos4=[240,20,80,30]; h4=uicontrol('style','push','string','Response','position',pos4) set(h4,'callback','responsefig');
Homework (I) • Design a user window interface, the operate environment as following : S 型曲線 四尖擺線 螺旋流線 1
Homework (II) – PID套裝軟体之設計 • 套裝軟体首頁之設計 • 按 ‘進入’, 程式進入之PID套裝軟体畫面 • 可自由設計 P , I , D 三個參數, 並繪製響應圖 • 參考文獻 MATLAB程式設計與應用: CHAPTER 6 : 影像顯示與讀寫 Mastering -MATLAB 6 CHAPTER 28 : Images , Movies , and sound
PID 控制參數之調諧 • x1=0;x2=0;dt=0.01;r=1;step=2000;kcp=200; • tcp=0.44; • kp=kcp*0.6;Td=0.125*Tcp;Ti=0.5*Tcp; • kd=kp*Td;ki=(kp/Ti);pe=r-x1;ie=(r-x1)*dt; • Ziegler-Nichols Tuning : 響應速度加快, 但超越量過大為最大問題 • 自行驗證一個最佳化之調諧參數
Uicontrol – POPUP / LIST • pos1=[335,23,80,24]; • h1= uicontrol ( 'style', 'popup', 'string' , ‘one|two|three|four|','position',pos1); • set(h1,'callback',‘sub_1'); • switch get(h1,'value') • case 1 • statement (subroutine1) ; disp('one') • case 2 • statement (subroutine2) ; disp(‘two') • end
Uicontrol – EDIT • pos2=[Left, Bottom, Width, Height]; • h2=uicontrol('style','edit','string',int2str(initial_x),'position',pos2,'backgroundColor',[1 1 1]); • pos3=[Left, Bottom, Width, Height ]; • h3= uicontrol('style','push','string','Test','position',pos3); • set(h3,'callback',‘sub_3'); • sub_3 subroutine • x=(str2num(get(h2,'string')))
Uicontrol – CHECK/RADIO • pos4=[450,20,80,20]; • h4=uicontrol('style','check','string','Grid on','position',pos4,'value',0); • set(h4,'callback',‘sub_4'); sub_4: • switch get(h4,'value') • case 0 • grid off; • case 1 • grid on; • end
