US Patent:
4276502, Jun 30, 1981
Filed:
Apr 28, 1978
Appl. No.:
5/900926
Inventors:
Harry S. Elliott - Houston TX
Assignee:

International Classification:
G05B 2302
US Classification:
318565
Abstract:
An improved alternating current prime mover control system and method for, for example, the control of a valve position or other physical variable whose state can be sensed or calculated wherein the state of the physical variable is compared with a reference variable to generate, in conjunction with a waveform generator, a fixed amplitude signal that has variable time duration which feeds a part of the control system that drives the alternating current prime mover source in more than one direction.
