“…The advantages of the Fuzzy Control and the PID control are integrated to design the fuzzy-PI controller by combining the SIMULINK and FUZZY tool box organically. The simulation results show that this control method greatly enhances the control effect of the nonlinear, hysteresis system, and improves the system's flexibility and adaptability (Panxiang et. al., 2011).…”

A mathematical model is developed to estimate the pressure response of an insulated electric air compressor. A pressure switch is modeled as a comparator and the electric motor as an amplifier. It is assumed that the compressed air is a perfect gas when applying the isentropic process. In addition, the effect of a step, ramp and sinusoidal functions of disturbance signals on the air pressure has been studied. A good agreement was obtained when comparing the predicted results with the measured values obtained from the experimental test that was done using a (1.32 kW, 23 litter and 8 bar) electric reciprocating air compressor. In addition, the same behavior of the predicted results was obtained when compared with results of a previously published article. It was found that the time constant of this control system is directly proportional with the value of the spring constant that is inserted inside the pressure switch and with the volume of air storage vessel, and it is inversely proportional with the gain of the amplifier and with the effective cross -sectional area of the pressure switch diaphragm and it is independent of the value of operating pressure set point. In addition, when the value of disturbance signal is positive, it will increase the output pressure response and when it is negative, it will decrease it.

The direct application of classical tuning methods in determining the PID controller parameters warrants the determination of the intercept values in X-axis (designated as " L" ) and Y-axis (designated as " a " ) from the open loop step response of the output (to be controlled) with respect to input signal (to be regulated). However, for complex processes, the above procedure seemed to be cumbersome and as an alternative step the researchers usually opted for the heuristic algorithms for the determination of PID controller parameters. In this paper, the authors have identified the boiler demand signal as the input signal to be regulated to control the steam pressure of utility steam generators and derived the PID controller parameters using classical tuning algorithms. Further, it has been demonstrated that with the use of these controller parameters, the transient responses obtained during fuel switching as well as load disturbances are much better than the earlier published results.
