nicholschart
ニコルス線図
呼び出し手順
sh = nicholschart(modules) sh = nicholschart(modules, args) sh = nicholschart(modules, args, colors)
引数
- modules
- 実数ベクトル: モジュール (単位: dB). Default values:
[-30:-10:Modmin -20 -15 -12 -9 -6 -3 -2 -1 -.5 -0.2 -0.1 0 0.1 0.2 0.5 1 2 3 6 12]
- args
- r実数ベクトル: 位相 (単位: 度). Default values:
-[1 2 5 10 20 30 50 70 90 120 140 160 180]°
- colors
- vector of 1 or 2 components specifying the colors of the isogain and isophase
sets of curves. If a single color is provided, it is used for both gains and
phases. colors may be specified either
- by indices in the color map.
- named colors among the predefined ones.
- "#RRGGBB" hexadecimal case-insensitive strings starting with "#", like "#FA7B35".
- A 1x3 or 2x3 matrix of [r g b] intensities with 0 <= r,g,b <= 1.
- sh
Structure with 3 fields:
.phaseLines
: vector of handles of isophase lines..phaseLines(i)
is the line forargs(i)
..gainLines
: vector of handles of isogain lines..gainLines(i)
is the line formodules(i)
..gainLabels
: vector of handles of isogain labels..gainLabels(i)
is the label formodules(i)
.

例
//ニコルス線図 clf subplot(1,2,1) nicholschart(); subplot(1,2,2) mod = [-35:5:-10 -6 -3 -1 -0.2 1 2 3 6]; nicholschart(mod, -[1 20 40 80 160 180],["khaki" "paleturquoise"]);
//ニコルス線図のグリッドを付けたブラック図 s = poly(0,'s'); Plant=syslin('c',16000/((s+1)*(s+10)*(s+100))); // 2自由度PID tau = 0.2; xsi = 1.2; PID = syslin('c',(1/(2*xsi*tau*s))*(1+2*xsi*tau*s+tau^2*s^2)); clf black([Plant;Plant*PID ],0.01,100,["Plant";"Plant and PID corrector"]); // 右下隅にキャプションを移動 gca().children(1).legend_location="in_lower_right"; h = nicholschart(,,'wheat'); h.gainLabels.font_foreground = color("orange");
