In order to solve the problem of the controlled multibody system dyanmics by multibody system transfer matrix method , the control actuator element transfer matrix and the control feedback element transfer matrix are introduced to create controlled multibody system transfer matrices which settle the dynamic question of controlled multibody system with delay and controlled multibody system without delay , to make the transfer matrix method of controlled multibody system apply to the field of controlled multibody system
摘要为用多体系统传递矩阵法解决受控多体系统动力学问题，该文引进控制激励单元传递矩阵和控制反馈单元传递矩阵，建立了受控多体系统传递矩阵法，解决延迟受控多体系统和无延迟受控多体系统动力学问题，使得受控多体系统传递矩阵法应用于复控多体系统动力学领域。
