Fluid-Loop Reaction System

View page
US Patent:
5026008, Jun 25, 1991
Filed:
Jan 31, 1990
Appl. No.:
7/473242
Inventors:
Boris J. Lurie - La Crescenta CA
J. Alan Schier - Tujunga CA
Theodore C. Iskenderian - Pasadena CA
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
International Classification:
B64G 128
US Classification:
244164
Abstract:
An improved fluid actuating system for imparting motion to a body such as a spacecraft is disclosed. The fluid actuating system consists of a fluid mass that may be controllably accelerated through at least one fluid path whereby an opposite acceleration is experienced by the spacecraft. For full control of the spacecraft's orientation, the system would include a plurality of fluid paths. The fluid paths may be circular or irregular, and the fluid paths may located on the interior or exterior of the spacecraft.

Torque Sensor Having A Spoked Sensor Element Support Structure

View page
US Patent:
4932270, Jun 12, 1990
Filed:
Mar 21, 1989
Appl. No.:
7/326820
Inventors:
Boris J. Lurie - La Crescenta CA
J. Alan Schier - Tujunga CA
Michael M. Socha - La Crescenta CA
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
International Classification:
G01L 300
US Classification:
7386233
Abstract:
Piezoelectric sensor devices are attached across pairs of circularly arranged spokes arrayed on the periphery of an annular ring. The sensor devices each include a preloaded steel ball mounting arrangement for mounting a piezoelectric sensor element. A first circular interface plate on one side of the sensor structure attaches to alternate ones of the spokes, and a circular interface plate on the opposite side of the same diameter as the first interface plate attaches to the remaining spokes.

Non-Linear Dynamic Compensation System

View page
US Patent:
5119003, Jun 2, 1992
Filed:
Oct 10, 1990
Appl. No.:
7/598902
Inventors:
Boris J. Lurie - La Crescenta CA
Assignee:
California Institute of Technology - Pasadena CA
International Classification:
G05B 1300
US Classification:
318561
Abstract:
A non-linear dynamic compensation subsystem is added in the feedback loop of a high precision optical mirror positioning control system to smoothly alter the control system response bandwidth from a relatively wide response bandwidth optimized for speed of control system response to a bandwidth sufficiently narrow to reduce position errors resulting from the quantization noise inherent in the inductosyn used to measure mirror position. The non-linear dynamic compensation system includes a limiter for limiting the error signal within preselected limits, a compensator for modifying the limiter output to achieve the reduced bandwidth response, and an adder for combining the modified error signal with the difference between the limited and unlimited error signals. The adder output is applied to control system motor so that the system response is optimized for accuracy when the error signal is within the preselected limits, optimized for speed of response when the error signal is substantially beyond the preselected limits and smoothly varied therebetween as the error signal approaches the preselected limits.

Balanced Bridge Feedback Control System

View page
US Patent:
4912386, Mar 27, 1990
Filed:
Mar 21, 1989
Appl. No.:
7/332677
Inventors:
Boris J. Lurie - La Crescenta CA
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
International Classification:
H02P 516
G05B 501
US Classification:
318615
Abstract:
In a system having a driver, a motor, and a mechanical plant, a multiloop feedback control apparatus for controlling the movement and/or positioning of a mechanical plant, the control apparatus having a first local bridge feedback loop for feeding back a signal representative of a selected ratio of voltage and current at the output of the driver, and a second bridge feedback loop for feeding back a signal representative of a selected ratio of force and velocity at the output of the motor. The control apparatus may further include an outer loop for feeding back a signal representing the angular velocity and/or position of the mechanical plant.

Three-Parameter Tunable Tilt-Integral-Derivative (Tid) Controller

View page
US Patent:
5371670, Dec 6, 1994
Filed:
Feb 1, 1993
Appl. No.:
8/023253
Inventors:
Boris J. Lurie - La Crescenta CA
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
International Classification:
G05B 1302
US Classification:
364160
Abstract:
A feedback control system compensator of the PID type is provided, wherein the proportional component of the compensator is replaced with a tilted component having a transfer function s to the power of -1/n. The resulting transfer function of the entire compensator more closely approximates an optimal transfer function, thereby achieving improved feedback controller. Further, as compared to conventional PID compensators, the TID compensator allows for simpler tuning, better disturbance rejection ratio, and smaller effects of plant parameter variations on closed loop response.
