中文摘要
      研究了具有线性耗散边界控制的Timoshenko梁的边界反馈镇定问题. 首先, 在反馈系数矩阵B正定的前提下, 我们证明了所论闭环系统是指数稳定的. 然后, 对于反馈系数矩阵B半正定的情况, 得到了闭环系统渐近稳定的几个充要条件.
英文摘要
      The stabilization problem of a Timoshenko beam with some linear boundary feedback controls is studied. First, under the condition that the feedback coefficient matrix B is positive, the energy of the corresponding closed loop system is proven to be exponentially convergent to zero as time t→∞. Then, under the condition that rank(B)=1, some necessary and sufficient conditions for the corresponding closed loop system to be asymptotically stable are derived.
