【摘要】 基于动态测量数据处理实践和学科发展的必要,作者构造了可考虑时变特性的时变参数自适应控制数学模型。对于此模型的算法关键是参数因子的选择,把参数序列作为参数函数的表达式,其参数是广义参数,在计算中是一可变值。在包括参数因子的目标函数下,得到了时变参数自适应控制算法公式,并与自适应控制模型一般公式作了比较。参数因子函数的表达依赖于所处理问题的信息相关性,文中给出了基本的选择值可供参考。更多还原

【Abstract】 Based on the necessity of data processing practice in kinematic surveying and its development,in allusion to the analysis objects of kinematic surveying practice,the author aim to construct adaptive control mathematic model with changeable parameters——the Adaptive Control with Time Varying Parameter.The key problem for the algorithm implement of this model is the choice of the parameter factors.The parameter sequence be used as the expression of the parameter function in this paper,and the parameter is the generalized parameter that different with the affiliation parameter in the conditional estimation theory.The parameter is a varying parameter in the computation（It is the common adaptive control when the parameter equal 1）.The algorithm formulae for the adaptive control with time varying parameter has been derived in the theory using the objective function that include parameter weight,the expressions the parameter funcetion depend on the realtionships of the information,such as α（k）=α₀α（k-1）+（1-α₀）,the suitable value for the parameter has been obtained using the iterative computation.更多还原
