This paper presents a graphical design method for common continuous-ti
me and discrete-time compensators, The method is based upon a set of d
esign charts which have been generated using appropriately normalized
compensator transfer functions, These charts allow compensator paramet
ers to be determined with minimum calculations, and without going thro
ugh the trial and error procedure presented in most introductory contr
ol systems textbooks, A detailed design example is given to illustrate
the method.
