Control Strategies for Complex Systems for Use in Aerospace Avionics.

Abstract

The research program was focused on investigating new methods of analysis, synthesis, and optimization of control systems particularly those which contain uncertain parameters and disturbance inputs. The objective was to develop methods to improve the performance of control systems by counteraction the effects of these random parameters and disturbance inputs. Several new methods which contribute to this objective were proposed and developed under this program. Among these new approaches are strategies for sensitivity adaptive feedback with estimation redistribution, sensitivity reducing compensators using observers, stochastic adaptive control of systems containing random parameters, control of singularly perturbed stochastic systems, trajectory optimization of singularly perturbed systems, time scale decomposition in regulator design, and high gain feedback systems and variable structure systems. The results obtained during the five year period are fully documented in 38 journal articles, 30 conference papers presented at various international congresses and national meetings, and 18 technical reports of the Laboratory. Some of these results were briefly summarized in four Interim Scientific Reports submitted annually during the grant period. (Author)
