The root locus method, developed by W.R. Evans, is widely used in control engineering for the design and analysis of control systems. In this method, the closed-loop system poles are plotted against the value of a system parameter, typically the open-loop transfer function gain. This method...
Root Locus (Matlab) 1. Root Locus 乃是根據不同的K 值畫出 ( ) ( ) P s KQ s + = 0之根軌跡的技術。 2. 典型的負回授控制系統,其閉迴路轉移函數為( )( ) ( )G sG s H s 1+,而其特徵方程式為( ) ( ) 1 0 + = G s H s 。 3. 假設 ( ) ( ) G s H s 可表示成...
Hi. I've been using matlab to plot root loci for my control systems class but I ran into a problem with a recent assignment. This particular problem asks me to plot the root locus of a system in which the transfer function has a variable gain in addition to numeric terms. I just ...

Open in MATLAB Online Hello, I need to plot the Root Locus with a chaging "k" of a given transfer function without using any special Matlab functions i.e., "rlocus", "tf". I'm allow to use roots. The code bellow displays an error/warning message(Subscript indices must ...
MatLab讲义五:Root-locus DesignMatLab講義五:Root-locus Design 一、根軌跡的基本觀念 K為控制增益 G(S)為轉移函數 H(S)為回授函數 閉迴路轉移函數 ∴極點滿足1+KG(S)H(S)=0→ 若S1是閉迴路的極點,即S1必須滿足 1.大小關係: 必為實數 2.相位關係:∠G(S1)H(S1)=±(2q+1)π0≦K<∞...
6.17. ROOT-LOCUS METHOD FOR CONTROL SYSTEMS USING MATLAB [7] InSections 6.14–6.16, several root-locus plots were generated using the 12 rules of construction and were hand drawn. Additionally, several root-locus plots were also illustrated which were obtained using MATLAB. In this section, the...
Since you have a good initial estimate (from the plot, as you mentioned), it would make sense to refine that estimate using fminsearch or fzero. I.e., write a function d(K) of the gain K that measures the difference between the modulus of the root a...
