A universal design chart for linear time-invariant continuous-time and discrete-time compensators

Recently, design charts were given for various conventional compensators. In particular, a design chart was developed for the phase-lead-lag compensator to eliminate the trial-anderror nature of the design. In this paper, it is shown that a single universal design chart can be generated for all the various types of conventional compensators. This chart allows compensator parameters to be determined readily and is applicable to the design of both continuous-time and discrete-time compensators. A detailed example is given to illustrate the use of the chart. This universal chart may be computerized for ease of design.
