| 摘 要： | 基于柔性梁的多刚性－弹簧系统模型，采用分段线性化的思想，由线性二次优化理论导出了有闭环反馈控制的以分段压电片为执行器的平面运动柔性杆梁结构非线性振动的主动控制的分析方法。两个算例验证了所提方法的有效性。

| Abstract: | A scheme for nonlinear active vibration control of flexible beam structure taking part in planar motion, where the segmented piezoelectric material, acting as actuators, constitutes a direct feedback closed loop control system. Based on the multi rigid spring system model, a computational method for obtaining the feedback gain matrix is derived by the linear quadratic optimal theory. Two examples are given to illustrate the feasibility of the present method. |
