12.3. Root Locus Plot Using MATLAB
A number of rules have to be followed for plotting the root locus by conventional method. However, it can be easily plotted by using predefined built-in functions in MATLAB. In general, the open-loop transfer function is given as
12.5.
where
n(s) is the numerator polynomial, and
d(s) is the denominator polynomial.
The characteristic equation of the closed-loop transfer function is given by
12.6.
To plot the root locus of the characteristic equation d(s) + Kn(s) = 0, rlocus command is used. The syntax ...
