Flight Test of Advanced Digital Control Concepts.

Abstract : The overall objective of this research is to investigate, via in-flight simulation, new and innovative digital control design concepts for six degree-of-freedom aircraft, including implication to flying qualities of digital mechanization. Factors such as emulation (Tustin transform) versus direct digital to analog coupler (zero-order hold versus slewer data hold) are the primary digital artifacts considered in this research effort.
