  1. Secondly, the effort is made to develope new type of transition element for multi - scale fatigue damage simulaton of long - span structures for the transition between elements for the hot spot stress analysis and the structural element. the linear and piecewise linear interplotion function for displacement interplotion are used for the transition element formulation according to the displacement compatibility requirement between element interfaces

    在綜合已有的構造過渡單元模型關于位移插值形式的基礎上，通過採用分段線性位移插值模式和線性位移插值方式，並在位移模式中引入非協調位移模式，強迫構造單元通過分片試驗，構造了一種用於疏密網格單元連接過渡單元。
  2. An off - line algorithm of constrained model predictive control based on piecewise - linear feedback control law is presented to solve its potentially high on - line computational demand. the piecewise - linear feedback control law is off - line computed by lmi optimization problems and the on - line control computation reduces to the simple evaluation of the defined piecewise linear function, which makes the online computational efficiency significantly improved. 4

    針對預測控制滾動優化命題的在線計算任務大，作者提出了一種基於分段反饋的離線預測控制演算法，通過離線求解線性矩陣不等式優化命題構造分段反饋控制律，在線運行時只需實施滿足條件的反饋控制律，極大地提高了控制器在線計算效率。
  3. The optimal control of uncertain piecewise linear systems is converted to the optimization of upper and lower bounds of the cost function

    摘要將不確定分段線性系統的最優控制問題轉化成最優控制性能上界的優化問題。
