Abstract : The development of a quickening term for the stabilization of high-order systems through the use of mathematical analysis together with analog computer simulation of the system dynamics and the design of appropriate circuitry modification are investigated. This method was developed to facilitate the design of an improved binary-type light display used in jet aircraft to indicate a 'too high' or 'too low' angle of attack condition. The mathematical analysis was effected through the use of Laplacian transform theory by means of which a synthesized simulation, structurally unlike but mathematically equivalent to the original simulation can be developed. The simplified configuration of this synthesized simulation facilitates the determination of the propert quickening needed to stabilize both the synthesized and the original simulation. Results of the test evaluation of the improved simulation show an increase in accuracy of almost four to one compared with the performance with a conventional display. (Author)
