工程结构主动控制中Riccati方程求解的改进

Improvement of Solution of Riccati Equation in Engineering Structure Active Control

由于建筑结构刚度和质量通常较大,对于Riccati方程的传统求解方法,常会发生计算溢出失效.为了避免该问题,本文对Riccati方程的求解进行了改进,并做了误差控制,表明本文的求解,是一种比较实用的改进方法.

Owing to the rigidity and mass of building structure larger, traditional solution of the Riccati equation may frequently produce calculating overflow and fail in computer. Consequently, this paper improves the traditional solution of the Riccati equation, and controls the calculating error. The resuh seems to indicate that the method of this paper may be more practical.
