Filed:

Jan 16, 2002

Appl. No.:

10/051617

Inventors:

Dennis K. Lee - Alhambra CA, US
Marvin K. Simon - La Canada CA, US

Assignee:

California Institute of Technology - Pasadena CA

International Classification:

H03D 3/22

US Classification:

375329, 375341

Abstract:

An FQPSK-B receiver uses a simplified trellis system which uses combinations of FQPSK-B waveforms to correlate against an input signal. This enables reduction of the number of correlators that are used and the number of comparisons that are made by the correlators.

International Classification:

G05B 501

US Classification:

318611

Abstract:

A servo control system for maintaining a direct current motor in operation at a constant speed is provided with two velocity feedback control loops. One feedback control loop is a rate damping loop which responds quickly to minor variations in motor speed to hold the motor at a predetermined command speed. The other loop is a steady state error loop through which a command speed is fed and which responds much more slowly to variations in command speed. The utilization of dual velocity control loops allows the servo system to adjust motor speed quickly in response to deviations in actual motor speed from commanded speed, yet is sensitive to low frequency variations in velocity feedback such as result from disturbances in motor loading.
