Adaptive Functions of Man in Vehicle Control Systems
Abstract
Inability of human pilots to introduce adequate adaptation of their control provided much of the motivation for the development of automatic adaptive control systems. The rapid change in vehicle system characteristics in high performance aircraft, which may climb from sea level to extremely high altitudes in minutes, required automatic adaptive control to relieve the burden on the operator.
This paper examines the principles and compositions of existing automatic adaptive control systems and on these bases the human adaptive as well as primary control functions are analyzed.
In general, human outshines the automatic system with his huge capacity of open loop or programmed control; but he lacks the capacity and speed for making on-line computations needed in the operation of active continuous adaptive system. Human can also perform some passive type or very simple active type adaptation but would require the assistance of a computer to perform complicated active adaptation.
This limitation is responsible for the domination of mechanized systems for adaptive control. There are advantages attributable to computer-assisted human adaptive control system considering the huge capacity of his open loop adaptation. Visual or some other form of multi-input display becomes a necessary medium when computer-man coupling is to be made effectively. Considering man’s remarkable ability of pattern recognition, this task may be in many cases easier than the coupling of a computer with an automatic actuator when a complicated function is to be recognized and manipulated.
