An automated virtual tool to compute the entire set of proportional integral derivative controllers for a continuous linear time invariant system

This thesis presents the very practical and novel approach of using the Graphical User
Interface (GUI) to compute the entire set of Proportional Integral Derivative (PID)
controllers given the transfer function or the frequency response of the system under
consideration.
Though there is a wide spread usage of PID controllers in the industry, until
recently no formal algorithm existed on determining a set of PID values that will
stabilize the given system. The industry still relies on algorithms like the Ziegler-
Nicholas or ad-hoc approaches in determining the value of PID controllers. Also
when it comes to model free approaches, the use of Fuzzy logic and Neural network
do not guarantee stability of the system.
For a continuous Linear Time Invariant system Bhattacharyya and others have
developed an algorithm that determines the entire set of PID controllers given the
transfer function or just the frequency response of the system. The GUI has been
developed based on this theory. The GUI also evaluates the user input performance
specifications and generates a subset of stable controllers given the performance criteria for the system.
This thesis presents an approach of automating the computation of entire set of stabilizing Proportional Integral Derivative (PID) controllers given the system
transfer function or the frequency response data of the system. The Graphical User
Interface (GUI) developed bridges the gap between the developed theory and the
industry.
