In Wang and Cluett (2000), a first order plus delay model was used to derive several tuning rules for PID controllers. The rules were calculated using a frequency response analysis based on the ratio of the time constant to the time delay , which is defined as . A desired closed-loop time constant is chosen as a scale of the time delay . Among them, which works quite well in applications, is a particular choice with the desired closed-loop time constant being equal to the time delay . For this choice, the PID controller parameters are presented in Table 1.6.
