A group of lesser used analog control system design techniques, generally termed parameter plane methods, is examined through the use of an IBM compatible microcomputer program developed as part of this thesis. The coefficients of a system's characteristic polynomial are determined by the plant and any added compensators. As these coefficients are varied , so too are the roots of the characteristic equation and therefore the system response in terms of bandwidth, settling time, etc. In the parameter plane method, a designer selects two parameters of a system's compensator(s) . The parameters commonly represent such attributes as a compensator gain, pole, or zero but can be any linear system function. One or more system characteristics dictating desired system performance, such as relative damping or undamped natural frequency, are computer model inputs. The associated parameter values to achieve the input characteristics are output in graphical and/or tabular form.
