| | Contrary to the tra- ditional way,separate design is made of the second- class weight of measurement,and then an combined optimun design of the two is effected through apply- ing the linear planning design method.The resultant design can be effectively used for determining the op- timum value of position parameter of network point and the optimal weight of measurement. | | 本文将传统的一类网形设计和二类观测权设计分开进行并采用线性规划设计的方法发展成将两类设计组合在一起进行监测网网形和观测方案的混合优化设计 ,并采用非线性优化设计方法求解监测网网点位置参数最佳值和最佳观测权。这比传统设计更切合客观实际、更科学、更合理。 | | 文摘来源 | | Taking the sensitivity criterion as the object function of the optimum design, the paper establishes the mathematical model for the combined optimum design of the deformation monitoring network. Aming at the conditions of thesemodels are unsolvable directly, the mathematical models are then transformed into non - linear optimum problems solvable by the non - linear optimum technique-constrained variable metric method. | | 该文以灵敏度准则为优化设计的目标函数,建立了变形监测网混合优化设计的数学模型。针对不能直接解算这类模型的情况,通过对数学模型进行变换,使之变为能够采用非线性优化技术──约束变尺度法解算的非线性优化问题。 | | 文摘来源 | | The mixed H 2/H ∞ optimal problem has received a special attention because it can attain perfect robust stability and performance. In this paper, generation, development, and characteristics of the mixed H 2/H ∞ optimal problem are introduced, the new development and practical applications are summarized.
