Abstract : As a result of research performed for the Air Force, two laboratory models of a single-axis, triple-redundant, self-adaptive flight control system were constructed. Both models demonstrate extensive use of integrated circuits; but one system employs analog circuitry, while the other is essentially a digital-differential-analyzer. An objective system comparison is achieved with an exponentially weighted figure of merit incorporating numerical measures of system effectiveness with respect to seven comparison criteria: complexity, cost, performance, power, reliability, volume, and weight. The unique TRISAFE analog redundancy method is the primary reason for the overall superiority of the analog system. (Author)
