摘要
用功率流指标描述主动隔振系统中能量的传输 ,以传输到接受体的功率流最小为最优化控制目标 ,推导主动隔振系统中功率流传递的最优控制表达式 ,提出了 SMR主动隔振模型基于功率流的最优化控制策略。针对工程实际中的柔性安装问题 ,对四边简支矩形薄板的主动隔振进行了研究。
The transmitted vibratory energy of the active isolation system is described by the performance index of the power flow,and the optimum control function of the active isolation system is developed,where the minimum power flow transmitted into the flexible receiver acts as the optimum function,and then the optimum control strategies of the power flow are presented based on the SMR model.In the end,aiming at the flexible installing of the practice engineering,the active isolation vibration of the rectangular thin plate,which is simply supported on the four sides,is investigated.
