Abstract:According to the performance characteristics of six degree of freedom (6-DOF) motion platform, the trajectory for the platform was planned based on an inverse solution of the position, the overall structure and the control system software and hardware of the platform were analyzed, and with “PC + with PMAC” for the structure, the 6-DOF platform motion control system was designed. The performances of a single cylinder position tracking and trajectory tracking were tested by experiments in using the control system. Test results verify the validity of the model, and the project feasibility and effectiveness of PID control based on RBF fuzzy neural network setting, which provides a convenient and efficient platform for further research of hydraulic 6-DOF motion platform in the future.
