12.22. Summary
The chapter can be summarized in following points:
The basic concepts of root locus technique, i.e. magnitude and angle condition are explained.
The use of MATLAB function rlocus to draw root locus is illustrated.
The plotting of root locus using plot command is also described.
Drawing of polar gridlines in root locus diagram using sgrid command is discussed.
rlocfind function, which is used to find gain K at a given point on the root locus, is illustrated with suitable examples.
The plotting of root locus for systems given in state-space representation is also described.
The basic concepts of frequency domain analysis of control system are discussed.
The use of bode and logspace functions to draw bode diagram is illustrated.
