Methods and systems for off-line control for simulation of coupled hybrid dynamic systems

A method of controlling simulation of a coupled hybrid dynamic system, comprising the steps of:

• driving a physical structural component of the system on a test rig by applying a drive signal input to the test rig to generate a test rig response as a result, and receiving the test rig response at a processor configured with a virtual model of the system and generating a model response of the system based on using a first part of the received test rig response as an input;
• comparing a different, second part of the test rig response with the model response corresponding to the second part of the test rig response to form a difference;
• and using the difference to form a system dynamic response model for generating the test rig drive signal.

A non-transient machine readable medium encoded with instructions for causing a processor to control simulation of a coupled hybrid dynamic system, the instruction comprising code for:

• driving a physical structural component of the system on a test rig by applying a drive signal input to the test rig to generate a test rig response as a result, and receiving the test rig response at the processor configured with a virtual model of the system and generating a model response of the system based on using a first part of the received test rig response as an input;
• comparing a different, second part of the test rig response with the model response corresponding to the second part of the test rig response to form a difference;
• and using the difference to form a system dynamic response model for generating the test rig drive signal.
