Available in PDF, EPUB and Kindle. Book excerpt: A manual pulse-frequency modulated reaction control is a control with fixed pulse width, fixed pulse amplitude, and manual control of pulse frequency. For such a control, it is possible to maintain a constant reactive force per pulse for various combinations of pulse widths and pulse amplitudes. The controlled element was a one-dimensional second order system. A semirandom sequence of three step voltages was used to displace a spot on a CRT. Subjects were required to recenter the spot as fast as possible. Manual control performance was tested under three levels (low, middle, high) of control output gain. Three pulse width-pulse amplitude combinations were tested at the low and high control output gain levels and four pulse width-pulse amplitude combinations for the middle control output gain level. Three subjects were tested under all conditions. Performance measures obtained were: integrated absolute error, integrated absolute fuel consumption, and integrated absolute stick motion. The results of this study indicate that (1) changing pulse width and pulse amplitude, but keeping control output gain fixed, does not affect manual performance; but that (2) changing control gain does.
