Improvements in the transient fidelity of HWIL flight tables using acceleration feedback

Control system architecture will help eliminate or reduce non-linear behavior of flight table axes motions. This elimination and reduction will help improve dynamic transparency in HWIL simulations. This paper presents the design, analysis and test results of a three-axis hydraulic flight table using acceleration feedback as a part of the axes servo structure. This approach significantly improves the transient motion of the axis under control producing a very high fidelity flight motion table.
