Structure design and anti-impact simulation analysis of unidirectional balancing unit based on control moment gyroscopes

To improve the slow shaking, impact, and other issues of high-rise building targets caused by strong winds, a novel balancing unit of anti-shaking and anti-impact control moment gyroscopes (CMG) is proposed based on the gyroscopic effect, and its anti-impact performance is analyzed by simulation. First, the structural design of the balancing unit was provided, and a dynamic model of the balancing unit was established using Lagrange’s equations. Second, a simulation of the control algorithm is conducted using both PID control based on the transfer function and sliding mode control (SMC) based on the approach law. Finally, based on the three-dimensional model and control algorithm, an anti-impact integrated simulation of the balancing unit was performed. The effectiveness of the designed control law and anti-impact technique was verified through simulations. It was concluded that the proposed novel balancing unit has good impact resistance and can provide a new solution for anti-shaking and anti-impact applications in high-rise building targets.
