US Patent:

6681182, Jan 20, 2004
Filed:

Feb 1, 2002
Appl. No.:

10/061499
Inventors:

Craig M. Heatwole - Redondo Beach CA
Louis K. Herman - Palos Verdes CA
Girard M. Manke - Huntington Beach CA
Brian T. Hamada - Torrance CA
Assignee:

The Aerospace Corporation - El Segundo CA
International Classification:

G01B 1126
US Classification:

701220, 35613901, 73178 R
Abstract:

A fault detection pseudo gyro emulates mechanical gyros by processing space system appendage measurement data and reaction wheel tachometer data within reference and control systems of a satellite to compute the vehicular bus angular velocity rate data by accounting for external torques, the momentum transfer between the satellite, the bus, and the appendages for providing accurate relative vehicular position and angular velocity rate data in an attitude reference and control systems now having accurate vehicular angular velocity rate data while enabling fault detection of hardware gyros and momentum sensors.

US Patent:

61077704, Aug 22, 2000
Filed:

Jan 26, 1999
Appl. No.:

9/236889
Inventors:

Richard S. Jackson - Lakewood CO
Girard M. Manke - Huntington Beach CA
Assignee:

Lockheed Martin Corporation - Bethesda MD
The Aerospace Corporation - El Segundo CA
International Classification:

G05B 501
H02K 702
G02B 2608
B64G 128
F16H 2702
US Classification:

318611
Abstract:

A control system stabilizes the flexible body bending modes of a space, airborne, or ground-based system, while providing angular position control of an oscillating mass connected to a counter-oscillating counterbalance. The actuating mechanism uses two drive motors to exert torques on the mass and counterbalance, respectively, under the control of a feedback controller. The controller has a first control channel generating a first torque command signal for the first drive based on the angular position of the mass, and a second control channel generating a second torque command signal for the second drive based on the angular position of the counterbalance and a torque cross-feed signal from the first control channel. The second control channel includes a notch filter for removing input frequencies in a predetermined bandwidth about the frequency of the first torque command signal. The same controller can be used to control the system in oscillation and for large angle repositioning of the mass and counterbalance.

US Patent:

62632647, Jul 17, 2001
Filed:

Jun 8, 2000
Appl. No.:

9/590569
Inventors:

Louis K. Herman - Rancho Palos Verdes CA
Craig M. Heatwole - Redondo Beach CA
Girard M. Manke - Huntington Beach CA
Brian T. Hamada - Torrance CA
Assignee:

The Aerospace Corporation - El Segundo CA
International Classification:

G01B 1126
G64G 132
US Classification:

701 13
Abstract:

A pseudo gyro emulates mechanical gyros by software processes by processing space system appendage measurement data and reaction wheel tachometer data within reference and control systems of a satellite using principals of conservation of momentum to compute the vehicular bus angular velocity rate data by accounting for external torque, the momentum transfer between the satellite, the bus, and the appendages for providing accurate relative vehicular position and angular velocity rate data as an integral part of attitude reference and control systems now having higher reliability, longer life times, lower power consumption, and more accurate vehicular angular velocity rate data generated within high bandwidth operations. A specific improvement is the use of a bias torque estimator for accounting for uncertainties in external torque estimations for accurate total system momentum computations.
