超低速高精度转台中摩擦力矩的动态补偿

Friction Dynamic Compensation for a Simulator with Ultra-low Speed and High Precision

该文分析了三轴飞行仿真转台的摩擦特性 ,并采用了一种新的摩擦模型(LuGre摩擦模型 )对转台中的摩擦力矩进行动态实时补偿。提高了转台精度 。

The friction characteristic in three axis flight simulation turn table is analyzed. A new friction model(LuGre friction model) is adopted in order to dynamically compensate the friction of simulator every time. And the accuracy of the simulator is improved, thus offering a new way for developing new types of simulator with better performance.
