| Abstract | 本发明公开了一种结构变量对控制性能影响函数的计算方法，主要解决现有的方法不能准确计算结构对控制的影响矩阵，且当系统矩阵奇异或者不稳定时无法求解的问题，其实现步骤是：首先以系统的线性二次型控制器LQR(Linear Quadratic Regulator)为基础，根据其最优性能指标，结合系统的最优KKT(Karush-Kuhn-Tucker)准则，得结构变量对控制性能的影响函数；然后基于精细积分原理，将作用时间分成时间步长为η的一系列时间间隔，根据加法定理，对基本区段进行合并，在每一步的合并计算中，主要对增量进行，避免合并时由于计算机的舍入操作引起的精度损失。本发明克服了传统的计算方法的缺陷，不但可稳定计算影响函数，而且精度非常高。 |
| Other Abstract | The invention discloses a calculation method for a structure-variable-to-control-performance influence function, which is mainly used for solving the problem that the prior art cannot accurately calculate a structure-to-control influence matrix and solves the problems that the matrix of the current system cannot be solved when being singular or unstable, The calculation method disclosed by the invention comprises steps of obtaining a structure-variable-to-control-performance influence function by basing on a LQR (linear quadratic regulator) and combining with an optimal KKT (Karush-Kuhn-Tucker) rule of the system according to an optimal principle index, dividing an action time into a series of time intervals with time step being Eta by basing on the high precision direct integration, and performing merging on basic segments according to an addition theorem, wherein, in every steps of merging calculation, the merging is performed on increment to avoid the accuracy loss caused by the round-off operation of the computer. The invention overcomes the fault of the traditional calculation method and steady calculates the influence function and is high in accuracy. |
