Designs of aircraft for the near future exhibit the desire for a greater amount of maneuverability. Direct force control enables the decoupling of the aircrafs motion from is attitude providing significant benefits to both civilian and military planes. And with the advent of the highly capable microcomputer, the control law incorporating this increase in maneuverability will most likely be implemented digitally. However, the information and results in the areas of direct force control and digital flight control are deficient. This project was undertaken to increase the data base in these areas through the use of a microcomputer mounted aboard the Variable-Response Research Aircraft. An Equivalent Stability Derivitive matching control law was developed digitally to enable the following modes: flat turn, lateral translation or acceleration, fuselage pointing, pure roll, and coordinate turn. A method was devised to command an aircraft motion whose integral is included as a state in the dynamic equation of motion. It is apparent from flight testing that probably as much attention must be devoted to human factors considerations as to the control law itself in order to develop an effective digital flight control system incorporating direct force control.
