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 ( ) ( )( )( ...
I have a transfer function, constant zeta, I need easy way to find the intersection point between root locus & zeta line. Now, after plotting root locus & zeta using sgrid function, I can find approximately correct intersection point by mouse draging. But I need exact point. You know, ...

Feedback gain values that pertain to pole locations, returned as a vector. The feedback gains define the trajectory of the poles thereby affecting the shape of the root locus plot. Whenkis not defined by the user,rlocusadaptively selects a set of positive gainskbetween zero and infinity, to...

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. ...
Design a compensator for an electrohydraulic servomechanism using root locus graphical tuning techniques.
The Modern Control System Theory and Design (MCSTD) Toolbox enhances the professional toolbox by not only plotting the root locus with “rlocus” but also calculating almost any point of interest on the root-locus plot directly (the professional version has only “rootfind,” a graphical method...
