Abstract
The present subject matter relates to systems and methods for active vibration control system speed monitoring and control in which a speed protection monitor configured to receive index pulses as inputs to monitor the speed of one or more force generators. A rotary actuator control system can be connected in communication with the speed protection monitor and the one or more force generators, wherein the rotary actuator control system is configured to shut down or adjust the speed of the one or more force generators if the one or more force generators are determined to be operating at undesired speeds.
Claims31
An active vibration control system (AVCS) for one or more force generator monitoring and control comprising:
- a rotary actuator control system in communication with one or more force generators, the rotary actuator control system configured to execute an active vibration control routine and to control the one or more force generators based on one or more first sensor signals received from a first sensing circuit of the rotary actuator control system;
- and
- an independent monitoring system operationally separated from the rotary actuator control system, the independent monitoring system configured to receive one or more sensor signals from a second sensing circuit of the independent monitoring system to monitor operating conditions of the one or more force generators, independently from the rotary actuator control system the independent monitoring system is configured to compare the one or more sensor signals to one or more reference signals corresponding to an under speed, an over speed, an over-vibration operating condition, and/or an incorrect force and shut down or adjust the operating condition of the one or more force generators in response to the comparison when the one or more force generators are exceeding an operating limit and operating at undesired conditions consisting of force, speed, vibration and combinations thereof, wherein the operating limit is based upon the design of the one or more force generators.
A method for active vibration control system (AVCS) monitoring and control, the method comprising:
- operating a rotary actuator control system to execute an active vibration control routine using one or more force generators based on one or more first sensor signals received from a first sensing circuit of the rotary actuator control system, wherein the rotary actuator control system is in communication with the one or more force generators;
- receiving, at an independent monitoring system operationally separated from the rotary actuator control system, one or more second sensor signals received from a second sensing circuit of the independent monitoring system to monitor operating conditions of the one or more force generators;
- comparing the one or more second sensor signals to one or more reference signals corresponding to an under speed, an over speed, and/or an over-vibration operating condition;
- and
- shutting down or adjusting, at the independent monitoring system and independently from the rotary actuator control system, the one or more force generators in response to determining, based on the one or more second sensor signals, that the one or more force generators are operating at undesired conditions consisting of force, speed, vibration and combinations thereof.
