Motion Drive Algorithm for Flight Simulator Based on the Stewart Platform Kinematics
To improve the fidelity of the motion cueing in the flight simulator, an improved adaptive motion drive algorithm was presented. In this algorithm, the motion limits of single degree of freedom, which calculate according to the Stewart platform kinematics, was introduced in to reduce the possibility of actuators exceeding theirs motion limits. So the algorithm parameters can be tuned more “open up” to improve the fidelity of motion cueing. The improved motion drive algorithm was verified in the airplane takeoff and landing. The results show that the algorithm can improve the fidelity when the platform has more available motion space; and can avoid exceeding motion limits when the platform has small motion space.
