Page 337 - ... 3. A perfectly definite set of rules for combining these processes into whole programs of processing. From a program it is possible to deduce unequivocally what externally observable behaviors will be generated. At this level of theorizing, an explanation of an observed behavior of the organism is provided by a program of primitive information processes that generates this behavior (Newell, Shaw and Simon, 1958b, p.

Page 11 - ... control is a multiloop task, while pitch and bank angle stabilization in straight and level flight is a multiple-loop task. Multiloop tasks involve, in general, more than one feedback quantity (eg, pitch angle and height) as well as one or more different pilot controls (eg, elevator and throttle). The inputs to the pilot may be perceived by only one of the senses (single modality) or by several senses (multimodality). Fixed-base simulation nearly always is limited to the single-modality case,...
Page 14 - ... learning and skill development phase, a particular multiloop system structure. The active feedback connections in this system will be similar to those which would be selected by a skilled controls designer who has available certain variable system characteristics to use for control of given fixed system characteristics; and who also has available a relative preference guide for the variables. System variables comprise sensing channels for each of the feedback possibilities available to the pilot,...
Page 14 - The equalization form and parameters are based on the "effective controlled element" with the inner loops closed, ie, the outer-loop Yc includes the augmenter-like action of the pilot in the inner loop. In general, feedback selections which involve much equalization, or different equalization in each loop, seem to be avoided by the pilot. A wide range of acceptable outer loop gains is desirable.

Page 14 - Crossover Frequency: The same crossover frequency considerations apply as for the single-loop case. Often the outer loop has a lower crossover frequency than the inner-loop or single-loop cases because of a larger accumulation of effective time delays.
Page 164 - Dunlap and Associates. Inc. The usual engineering models of the human operator employ techniques that were first developed in control engineering to describe and model control mechanisms. If there are ways in which the human operator differs from inanimate control mechanisms that are significant for...
