View pageUS Patent:
49995839, Mar 12, 1991
Filed:

Appl. No.:
7/486574
Inventors:
Robert D. Washburn - Malibu CA

Robert S. Wedeen - Manhattan Beach CA
Assignee:
Hughes Aircraft Company - Los Angeles CA
International Classification:
H03G 330
US Classification:
330 86
Abstract:
An amplifier drive control circuit having a power combiner for combining an RF input signal with a feedback signal to provide a composite RF signal, a power control circuit for providing a selectively attenuated replica of the composite RF signal to the input of the amplifier, and feedback circuitry connected between the output of the amplifier and the power combiner for providing a level controlled portion of the output of the amplifier as the feedback signal. The power control circuit selectively attenuates the replica of the composite RF signal when the power of the composite RF signal exceeds a predetermined threshold, while the feedback circuitry controls the level of the feedback signal as a function of the gain of the amplifier as determined by the level of the composite RF signal and the level of the amplifier output. The feedback circuitry includes a feedback phase control circuit for controlling the phase of the feedback signal relative to the input to the amplifier.

Assignee:
Hughes Aircraft Company - Los Angeles CA
International Classification:
H02P 700
US Classification:
318432
Abstract:
A torque oscillation compensation system and circuit that uses torque transducer feedback derived from an output shaft of an electric vehicle motor to compensate for electrical motor pulsations such as are experienced in an electric vehicle. A torque input source provides a torque input signal, that is coupled to a summing circuit. A controller is coupled to the summing circuit, and power switching circuitry is coupled between the controller and the electric motor. A torque transducer is coupled to the output shaft of the motor to sense torque pulsations. An oscillation compensation circuit is coupled between the torque transducer and the summing circuit that generates a feedback compensation signal that is combined with the torque input signal to compensate for output shaft oscillators. The oscillation compensation circuit comprises a loop amplifier having a predetermined transfer function and is coupled to the torque transducer, and AC coupling circuitry, typically comprising a plurality of coupling capacitors, coupled between the loop amplifier and the summing circuit. A limiter circuit comprising first and second oppositely coupled diodes may be coupled to a point between the AC coupling capacitors.

International Classification:
H03F 100
H01P 5107
H01P 5107
US Classification:
330 66
Abstract:
A new amplifier module construction enhances the manufacturer's ability to repetitively construct multiple copies of millimeter microwave amplifiers having performance characteristics that are consistent with one another, particularly in input VSWR ratio characteristic, and which performance characteristic do not significantly change following any necessary rework of the amplifier module, including any MMIC chip replacement. In this module, a waveguide to microstrip transition is formed of a backshort member that is separate from the metal base or cover and that backshort member is held pressed in place against the substrate by force exerted by the module's cover plate through a spring member against the exterior of the backshort member. The spring member is formed by a resilient compressible gasket.

Hughes Aircraft Company - Los Angeles CA
International Classification:
G05B 500
US Classification:
318632
Abstract:
A torque oscillation compensation system and circuit that uses motor speed to compensate for electrical motor torque pulsations. An input source provides a torque/current command input signal that drives the motor by way of a controller, and a summing device has one input coupled to receive the torque/current command input signal. A controller is coupled to power switching circuitry that is coupled between the power source and the electric motor. A speed sensor is coupled to the motor and is adapted to provide a motor speed output signal. An oscillation compensation circuit is coupled between a speed sensor and the summing device that generates a compensation signal in response to the motor speed output signal that is combined with the torque input signal and compensates for output shaft oscillations. The oscillation compensation circuit comprises an AC coupling capacitor, an amplifier that produces a predetermined phase shift that is designed to provide for the proper amount of compensation and cancel out the torque ripple in the drive signal.
