The root locus of an (open-loop) transfer function is a plot of the locations (locus) of all possible closed-loop poles with proportional gain K and unity feedback. The closed-loop transfer function is: (1) and thus the poles of the closed-loop poles of the closed-loop system are values of such that . RLOCUS(SYS) or RLOCUS(NUM,DEN) computes and plots the root locus of the single-input, single-output LTI model SYS. The root locus plot is used to analyze the negative feedback loop. BODE(SYS) or BODE(NUM,DEN) draws the Bode plot of the LTI model SYS. The frequency range and number of points are chosen automatically. Root Locus Analysis and Design K. Craig 31 • Useful Construction Rules for Negative Feedback – The number of branches of the root locus is equal to the number of poles of the open-loop transfer function. – For positive values of K, the root locus exists on those portions of the real axis for which the total number of MATLAB Control System Toolbox Root Locus Design GUI MATLAB Control System Toolbox contains two Root Locus design GUI, sisotool and rltool. These are two interactive design tools for the analysis and design of the singleinput single-output (SISO) linear time-invariant (LTI) control systems. sisotool opens the SISO Design Tool with Root Locus View and Bode diagram. rltool opens the SISO Design ...

RLOCUS(SYS) computes and plots the root locus of the single-input, single-output LTI model SYS. The root locus plot is used to analyze the negative feedback loop and shows the trajectories of the closed-loop poles when the feedback gain K varies from 0 to Inf. RLOCUS automatically generates a set of positive gain values that produce a smooth plot. While MATLAB can easily plot the root locus using the rlocus command, understanding the root locus building rules can be useful, they are: The number of roots in equation (5.6.5) is equal to max{m, n}. Thus, the root locus has max{m, n} branches. From equation (5.6.2), we observe that s 0 belongs to the root locus (for λ ≥ 0) if and only if
