A new digital control technique, called Model Algorithmic Control MAC, was applied to a single-input single-output model containing complex eigenvalues. The MAC algorithm developed was a simplified version of the algorithm used by ADERSAGERBIOS Corporation France in a complete computer program designated IDCOM Identification and Command. A second-order model based on the dominant eigenvalues of the B-52E Flutter Mode was selected as the hypothetical system to be controlled. Data were obtained for various selections of control parameters in the implementing program, then a study was made of the controlling programs robustness to eigenvalue changes. The second-order model was subsequently expanded to a third-order, then a fourth-order model, while maintaining the previously found optimum control parameters. Results obtained indicated that the robustness exhibited in the MAC concept as implemented in IDCOM is not attributed to the impulse response prediction technique, but rather must be attributed to the particular control algorithm used in IDCOM. Therefore, before conclusive results could be obtained for robustness and higher-order model studies, further refinement of the simplified MAC algorithm used in this thesis was necessary. A revision to the implementing program was begun, but due to time considerations, was not completed. Author
