Design of Robust PI/PID Controller for a Parametric Uncertain Jet Engine Using PSO

Uday Babu Oleti | Dr. M. Siva Kumar

Abstract: The modern jet engine consists of various control loops and subjected to several disturbances. The design of controller under the presence of parametric uncertainties is a difficult task. In this paper, an interval analysis is proposed for design of a robust PI/PID controller for jet engine. The proposed method applied to acceleration control loop of a jet engine in the presence of parametric uncertainties. The proposed method uses necessary and sufficient conditions for stability of interval polynomials. These conditions are used to derive a set of inequalities in terms of the controller parameters which are solved and find the optimal control parameters with the help of particle swarm optimization. The results show the efficiency of the proposed topology.
