摘要:
For the vibration control of the Canton Tower, the implementing strategy of AMD control device driven by multiple linear motors was presented. The performance tests of the directive force, feedback driving force, actual driving force, control system, velocity limitation by software, stroke limitation by software, control-force homogeneity and time lag of subsystem AMD1 and AMD2 control device driven by multiple linear motors were carried out, and the identification method and the calculation formulas of ripple thrust and comprehensive resistance force for AMD control device driven by multiple linear motors were proposed. The results of actual test for AMD control devices driven by multiple linear motors in the Canton Tower show that the implementing strategy of AMD control device for vibration control of the Canton Tower is feasible. Two subsystems AMD1 and AMD2 can receive and achieve driving force and the security system with stroke limitation and velocity limitation by software have outstanding performances. Meanwhile, the identification method and the calculation formulas of ripple thrust and comprehensive resistance force are suitable for identifying the AMD performance, and the subsystem AMD1 and AMD2 can implement the control force synchronously and have very small time delay, which can meet the requirement of vibration control for the Canton Tower. ©, 2015, Science Press.
