本文详细地阐述了递推辨识算法中的移位结构,由此导出了一种快速算法。这种算法所需的存贮容量与算术运算次数要比常规算法低一个数量级,因此在一定程度上提高了算法的实时性,便于在有限存贮容量与算术运算速度的微型机上实现实时控制和自适应控制。最后,本文通过数值仿真例子,进一步说明了这种算法所具的优越性。 In this paper, the shift structure in recursion identification algorithm is elaborated, and a fast algorithm is derived. This algorithm requires less storage capacity and arithmetic operations than the conventional algorithm by an order of magnitude, so to some extent, improve the real-time algorithm for easy storage and arithmetic speed limited operation of the microcomputer to achieve real-time control and Adaptive Control. Finally, this article further illustrates the superiority of this algorithm by numerical simulation examples.
