Abstract:

The purpose of this study was to develop a design concept for a programmable digital autopilot for terminally guided, lock-on-before-launch, air-to-surface weapons. The digital autopilot is to perform all the stability and control functions normally performed by an analog autopilot. The study activity encompassed four major tasks control requirements, digital control theory and system synthesis, digital mechanization, and a simulation and sensitivity study. The primary result of the study is the definition of a digital autopilot with the capability of being programmed to control and steer any lock-on-before-launch guided weapon. The baseline design utilizes AD conversion accuracy of 12 bits, DA conversion accuracy of 8 bits, scaling coefficient word lengths of 12 bits and data words of 20 bits. The simulation and sensitivity study indicated that the missile performance, with the defined digital autopilot, was unchanged from that obtained with an equivalent analog autopilot. Author
