Abstract

Abstract: To improve the control accuracy of flight simulator motion system, a kinematic error analysis and calibration based on relative visual pose measurement of electric Six-DOF Stewart platform were proposed. Considering the structural characteristic of Stewart platform, a rotary compensation algorithm was concerned firstly to raise the control accuracy. Then kinematic error model and optimal calibration algorithm were established, according to kinematic equations and vector closed-loop characteristic. Latterly, pose data was achieved using Basler industrial camera and ID marker featured by CRC (Cyclic Redundancy Check) and FEC (Forward Error Correction). Finally, measurements and experiment results supported the validity of the algorithm and higher control precision was obtained.
