Abstract
A system includes a frame and a plurality of machines mounted on the frame, wherein each machine of the plurality of machines includes an actuator, and wherein each machine is configured to operate in a defined condition. The system further includes at least one controller configured to control the actuators so as to exert an excitation of each machine of the plurality of machines. The system further includes at least one sensor configured to measure at least one response indicator of a response of the system to the excitations of the plurality of machines. The system further includes a diagnosis system configured to receive the at least one measured response indicator.
Claims20
A system comprising:
- a frame;
- a plurality of machines mounted on the frame, wherein each machine of the plurality of machines comprises an actuator, and wherein each machine of the plurality of machines is configured to be operated in a defined condition;
- a plurality of individual controllers configured to control the actuators of the plurality of machines so as to exert an excitation of each machine of the plurality of machines;
- an overriding controller configured to coordinate control of the plurality of individual controllers with predetermined offsets in time;
- at least one sensor configured to measure at least one response indicator of a response of the system to the excitations of the plurality of machines;
- and
- a diagnosis system configured to receive the at least one measured response indicator.
A method comprising:
- operating each machine of a plurality of machines mounted on a frame in a defined condition, each machine of the plurality of machines having an actuator;
- controlling each actuator of the plurality of machines, by a plurality of individual controllers, so as to exert an excitation of each machine of the plurality of machines;
- coordinating, by an overriding controller, control of each individual controller of the plurality of individual controllers with predetermined offsets in time;
- measuring, by at least one sensor, at least one response indicator to the excitation of each machine of the plurality of machines;
- and
- receiving, by a diagnosis system, the at least one measured response indicator.
