Design & Validation of LQG Controller for IDSN32 Antenna Control Servo System

Abstract

This paper presents the results of LQG (Linear Quadratic Gaussian) controller realization in one of the 32m diameter antenna axes at the Indian Deep Space Network (IDSN) near Bengaluru. The dynamic performance results are compared with that of the classical Proportional-Integral (PI) controller as well as the simulation results. Test results validate the simulation predictions, permitting larger gains, bandwidth and improved command response. These studies demonstrate the feasibility and benefits of realizing the LQG controller in the Indian Deep Space Network antenna - IDSN32.
