A Flight Investigation of Digital Control Using Microprocessor Technology.

Abstract

A microprocessor-based digital flight control system (Micro-DFCS) is implemented in Princeton's Variable-Response Research Aircraft (VRA), and evaluated through flight testing. The flight control computer program, CAS-1, provides three longitudinal control options; direct (unaugmented) command, pitch rate command, and normal acceleration command. The latter two options are Type 0 systems designed by linear-quadratic control theory. The flight tests are designed to investigate the characteristics of these control laws in flight, to provide experimental evidence for sampling rate requirements, and to demonstrate digital flight control of the VRA with the Micro-DFCS.
