APPLICATION OF LINEAR OPTIMAL CONTROL THEORY TO THE FLEXIBLE BOOSTER.

Abstract

A brief development of concepts and mathematics involved in frequency plane optimization, using a least integral error square with quadratic constraint performance index, is presented. The technique is applied to the problem of controlling a hypothetical flexible booster with quadratic constraint on the control. Problems arise from a RHP zero in the model of the booster. Results agree with results using conventional methods. Realizable compensation to yield a stable system could not be found. In contrast to conventional methods, this optimization technique allows precise solution. Trail and error and experience factors are minimized. Comparison with state space optimization shows frequency plane techniques superior in single input problems. (Author)
