Methods and systems for off-line control for simulation of coupled hybrid dynamic systems
First Claim
1. An arrangement for controlling simulation of a coupled hybrid dynamic system, comprising:
- a physical test rig configured to drive a physical structural component of the system and to generate a test rig response comprising a first component and a second component as a result of applying a drive signal input to the test rig; and
a processor configured with a virtual model of the system, the processor receiving the first component of the test rig response and generating a model response of the system based on using the first component of the received test rig response and a virtual drive as inputs;
the processor further configured to compare the second component of the test rig response with the model response corresponding to the second component to form a difference, the difference being used by the processor to form a system dynamic response model for generating the test rig drive signal.

Abstract
Systems and methods are provided for controlling the simulation of a coupled hybrid dynamic system. A physical test rig configured to drive the physical structure component of the system and to generate a test rig response as a result of applying a test rig drive signal. A processor is configured with a virtual model of the system. The processor receives the test rig response and generates a model response of the system based on the received test rig response and a virtual drive input. The system is driven with a random input. The processor compares the test rig response with the model response, the difference being used to form a system dynamic response model for generating the test drive signal. An inverse of the system dynamic response model is used to iteratively reduce the difference between the model response and the test rig response below a defined threshold.
