Design of Robust Controllers for Turret-Gun System Using Reduced Order Models

Abstract

Reduced order modeling techniques are used to design lower order robust controllers for a turret-gun system. The balance truncation, Routh approximation, Litz's modal techniques are used to derive reduced order models. A critical comparison to time and frequency response characteristics between original and reduced order models is made. The linear quadratic Gaussian with loop transfer recovery (LQG/LTR) methodology is employed to design robust controllers using reduced order models. The spillover problem associated with a reduced order model design procedure is also investigated. The frequency shaped linear quadratic regulator (FSLQR) with output feedback design methodology is also presented in this report. (sdw)
