The ease implementation, the simple mechanism and robustness of PID controllers has attracted the use of these controllers in the process industries. There are numerous tuning techniques are available for tuning of PID controllers. In this research work, in the first part basically a first-order plus dead time (FOPDT) model is developed and tuning of PID controller is done by using the Ziegler -Nichols method and then in the second part tuning is done using Lambda (λ) tuning method. The comparative and quantitative analysis is also done here for these two methods by taking some suitable examples. Here a quantitative and comparative analysis of the original higher order systems and the reduced FOPDT systems (modelled by Ziegler-Nicholas), is done to compare the various parameters like, settling time, rise time, transient time, peak overshoot, peak time etc. and then the unit step response and overall response for both the systems has been plotted and analyzed by using both the techniques.
Keywords:
FOPDT, PID controller, Ziegler Nichols, Lambda-Tuning, settling time, Tuning, rise time, peak overshoot.
