The Synthesis of Multipoint Quasi-Optimal Feedback Control Laws for Non-Linear Systems via Minimum Sensitive Trajectories.
Abstract
The thesis considers a multipoint quasi-optimal feedback control law which makes use of multiple optimal state and control histories to generate a set of feedback coefficients that are functions of the system's independent variable. These feedback coefficients are used, in conjunction with both the system's states and the independent variable, to generate a linear quasi-optimal feedback control law for controlling a non-linear dynamic system. A family of quasi-optimal feedback control laws is obtained for an aircraft landing problem in which the trajectories and control histories, used to synthesize the control laws, are obtained from solutions of optimal control problems reflecting minimization of the system's sensitivity coefficients. In this study, sensitivity coefficients are defined as mathematical descriptors that relate changes in the system's states at any time t to errors in the terminal state at the final time t sub f.
