Development of a Torque Sensor -Based Test Bed for ACS Verification & Validation
Abstract
The proposed research effort is fundamental in nature and targeted towards the development of a technology that will enable realistic hardware-in-the-loop (HIL) testing of attitude control systems. A high precision, high bandwidth torque sensor will be developed to directly assess the performance of attitude control systems (ACSs) rather than the indirect inference approach used by air bearing simulators. The capability to accurately characterize the output of attitude actuators and the performance of the underlying ACS algorithms benefits lean design of ACS for future spacecraft. Further, the ability to perform realistic simulations of entire mission scenarios is extremely beneficial for mission assurance and replication of on-orbit incidents. The HIL testing enabled by the proposed technology will provide new capabilities for spacecraft manufacturers and researchers involved in the development of new ACS technologies. The technology will enable verification and validation of advanced ACS technologies for future spacecraft being developed across-the-board including DoD, NASA, commercial agencies, and universities. The proposal does not include any hardware as a deliverable to the Air Force, but a working prototype will be developed to evaluate the efficacy of the proposed technology.
