部分施控振动系统的最优主动控制

THE ACTIVE OPTIMUM CONTROL OF THE PARTIALLY CONTROLLED VIBRATION SYSTEM

研究部分施控振动系统的最优主动控制问题，提出满足系统平均振动能最小的状态反馈控制律，导出时间离散数字控制系统的最优控制矩阵，并以Ｓ１９５型内燃机为例，模拟了整机振动的最优数字控制过程，效果理想．

Based on the concept of subsystem controlled and subsystem non-controlled, theactive optimum control of the partially controlled vibration system is investigated in this paper.The state feedback control law is presented to meet the needs of the minimum vibration energy,and an optimum control matrix of the discrete digital control program is formulated. Take modelS195 internal combustion engine as a simulating object. The optimum control process of the wholeengine vibration is simulated. The result shows that the present method is useful and the control iseffective.
