摘要
本文研究了结构振动及其控制系统差分方程统一模式的建立问题。对状态变量的观测,仅测量结构的前几个位移或速度。将随机输入和观测噪声等维化处理后,建立了结构振动及其控制系统差分方程的统一模式。
The unified differential equation of structure vibration and control systems is studied in the paper. The first few steps of displacements of the structure are measured. The unified differential equation is developed after making the stochastic excitation and observation noise be of equal dimensions.
