Research on High-Precision Attitude Control of Joint Actuator of Three-Axis Air-Bearing Test Bed by Zhiming Chen, Zhouhuai Luo, Yunhua Wu, Wei Xue, Wenxing Li

“…When the three-axis air-bearing table is maneuvering at a large angle, if it is only controlled by the flywheel, it will cause the problems of slow maneuvering speed and high energy consumption, and when the external interference torque becomes large, the control accuracy will decline. A combined actuator including flywheel, air-conditioner thruster, and automatic balancing device is designed, and a hierarchical saturation PD control algorithm is proposed to improve the control accuracy and anti-interference ability of the three-axis air-bearing test bed. …”
