Model Order Reduction and Linear Quadratic Regulator Controller Design on A Large Scale Linear Time Invariant System

Abstract

The main objective of this paper, aims to apply model order reduction on a large scale system and design a Linear Quadratic Regulator (LQR) based controller, to analyse the performance indices, in the time and frequency domains. Control aspects of large scale systems (models with very high order) are a major concern, in the field of control systems. The order of the designed controller must be close to the order of the large scale system, or even more in most cases. As the order of the controller increases the control aspects of the system, it becomes even more complex.
