Controllability and observability of transfer matrix method for linear controlled multibody system

The research on vibration characteristics and control of multi-body system is a research focus in the field of mechanical system dynamics and control engineering. For the controlled multibody system, the transfer equation of controlled element and the total transfer equation of the controlled system are derived in this paper, and the controllability and observability of the transfer matrix method for linear controlled multibody system are analyzed. An example simulation shows that the transfer matrix method for linear controlled multibody system is effective, The engineering application of controlled multibody system transfer matrix method has important theoretical and practical significance to solve a series of major engineering problems in the field of controlled multibody system dynamics and control.
