The Middeck Active Control Experiment (MACE) is a space shuttle flight experiment, manifest for launch on STS-67 on March 2, 1995, intended to demonstrate high authority active structural control in zero gravity conditions. Since no experimental on-orbit data is available before flight, the model used to derive these controllers must be obtained from a combination of analysis and open- and closed-loop ground testing. A general modeling approach to obtain this 0-g model is presented along with its application to the MACE test article. This modeling approach starts with a 1-g model, which includes gravity and suspension effects on the structure. This 1-g model is improved using ground test results in a process called updating. Once the model has been updated, it is verified through a combination of structural perturbation and closed-loop control. Finally, after the model has been verified, the gravity and suspension effects are removed to arrive at a prediction of the 0-g behavior of the structure.
