Abstract
The invention generally relates to stabilizing an amplifier. In one aspect, a stabilization module that is in electrical communication with the amplifier is provided. The stabilization module includes both an open loop control system and a closed loop control system. The open loop control system is used to modify at least one characteristic of an input signal received by the stabilization module and to pass control to the closed loop control system. The closed loop control system is then used to modify the at least one characteristic of the input signal. The modified input signal is provided to the amplifier.
Claims19
A method for stabilizing an amplifier, the method comprising:
- (a) providing a stabilization module in electrical communication with the amplifier and comprising an open loop control routine and a closed loop control routine;
- (b) using the open loop control routine to modify at least one characteristic of an input signal received by the stabilization module when a criterion for using the open loop control routine is satisfied;
- (c) passing control to the closed loop control routine;
- (d) modifying the at least one characteristic of the input signal with the closed loop control routine;
- and
- (e) providing the modified input signal to the amplifier.
A system for use in a stabilization module for stabilizing an amplifier, comprising:
- a first control module for receiving a first signal representative of an input signal received by the stabilization module, for generating a second signal capable of being used to modify a first characteristic of the input signal using an open loop control routine, and for sending a third signal capable of being used to pass control to a second control for sending a third signal capable of being used to pass control to a second control module;
- and
- the second control module for generating a fourth signal capable of being used to modify the first characteristic of the input signal using a closed loop control routine.
A method for stabilizing an amplifier, the method comprising:
- (a) providing a stabilization module in electrical communication with the amplifier and comprising an open loop control routine and a closed loop control routine;
- (b) using the open loop control routine to modify at least one characteristic of an input signal received by the stabilization module and to pass control to the closed loop control routine;
- (c) using the closed loop control routine to modify the at least one characteristic of the input signal if the criterion for using the closed loop control routine is satisfied;
- and
- (e) providing the modified input signal to the amplifier.
A computer program product, tangibly embodied in an information carrier, the computer program product including instructions being operable to cause data processing apparatus to:
- receive an input signal with a stabilization module comprising an open loop control routine and a closed loop control routine;
- use the open loop control routine to modify a characteristic of the input signal;
- pass control from the open loop control routine to the closed loop control routine to further modify the characteristic of the input signal;
- and
- provide the modified input signal to an amplifier.
