【摘要】 根据柔性体结构控制的特点，提出了结构振动控制的应变反馈方法。首先给出了与内力等价的、以应变表示结构的运动方程。在此基础上讨论了采用结构的应变信号反馈及控制结构振动的可行性。结果表明，结构的振动和应力可以同时得以控制，并且具有相同的衰减速率。最后，指出了存在的问题。更多还原

【Abstract】 The strain feedback control method,which based on the property of the control of flexible structure ,is introduced. First ,the strain motion equation which is equivelent to the displacenent motion equation is derived,then the feasibility of us-ing structure,s strain to control the vibration of the structure is discussed. The con-dusion is that the vibration and stress of the structure and stress can simultaneous-ly be surpressed and they the same decaying rate.更多还原
