Suppression Method

To restrain the interference of micro-vibration caused by Control Moment Gyroscope, a new control method based on Magnetorheological damper was proposed in this paper. A mechanical model based on the structure of the presented design was built, and the semi-active control algorithm of damping force was proposed for the designed Magnetorheological damper. The magnetic flux density and other magnetic field parameters were considered and analyzed in Maxwell, and also the related hardware circuit which implements the control algorithm was prepared to test the presented design and algorithm. The results of simulation and experiments show that the presented Magnetorheological damper model and semi-active control algorithm can complete the requirements, and the vibration suppression method is efficient for Control Moment Gyroscope.

For the sake of improving the agility and super-static performance of spacecraft, this paper puts forward an idea for using single gimbal magnetically suspended control moment gyroscope pyramid configuration to realize dual control of attitude maneuver and micro-vibration suppression of spacecraft, in which gyro gimbal rotation is used to realize fast attitude maneuver and magnetic suspension rotor deflection is used to realize high-precision micro-vibration suppression of spacecraft; the switching design of spacecraft attitude/vibration controller realizes the coordinated operation of gyro gimbal and magnetic suspension motor, showing the control advantage of dual actuators. This strategy not only speeds up the attitude maneuver process of spacecraft, improving the dynamic response, but also reduces the attitude stabilization adjustment time as well as improves the stabilization precision, ensuring the fast vibration suppression after attitude maneuver. In addition, this method has strong robustness ensuring the smooth implementation of spacecraft attitude control and vibration suppression integration in the case of parameter change. The simulation results show the effectiveness and superiority of this strategy.

Electric Bicycle

In recent years, researchers from both academia and industry have worked on connected and automated vehicles and they have made great progress toward bringing them into reality. Compared to automated cars, bicycles are more affordable to daily commuters, as well as more environmentally friendly. When comparing the risk posed by autonomous vehicles to pedestrians and motorists, automated bicycles are much safer than autonomous cars, which also allows potential applications in smart cities, rehabilitation, and exercise. The biggest challenge in automating bicycles is the inherent problem of staying balanced. This paper presents a modified electric bicycle to allow real-time monitoring of the roll angles and motor-assisted steering. Stable and robust steering controllers for bicycle are designed and implemented to achieve self-balance at different forward speeds. Tests at different speeds have been conducted to verify the effectiveness of hardware development and controller design. The preliminary design using a control moment gyroscope (CMG) to achieve self-balancing at lower speeds are also presented in this work. This work can serve as a solid foundation for future study of human-robot interaction and autonomous driving.
