Abstract:

The purpose of the thesis was to design a simple state-variable feedback system to control a linear plant with variable coefficients. The solution of the problem was to determine the values of the constant feedback gains based on a desired transfer function. This transfer function met all required time responses. One of the state-variables is an internal state and not available for measurement. This state is reconstructed using a minor-loop feedback circuit. A nominal set of conditions was selected for the plant and the feedback coefficients determined as a function of the nominal plant parameters and coefficients of the desired transfer function. Using the values of feedback coefficients determined above, the response of the control system was simulated at several flight conditions. Modified author abstract
