方波脉神函数及其应用——高阶线性定常模型的简化

Application of Block-Pulse Functions——Reduction of the Order of Linear Time-Invariant System Models

介绍了一种利用方波脉冲函数进行高阶线性定常系统简化的新方法,利用与Laplace变换中S算子相等效的矩阵1/hQ进行连续模型的简化;利用延迟矩阵D_k进行离散模型的简化。该算法结构简洁,运算速度快,计算精度高.

A new method is presented for the reduction of the order of a linear time-invariant system model with block-pulse functions. The reduction procedures are discussed in this paper, the continuous model is reduced with the matrix Q/h equivelent to operator 'S' in the Laplace transform and the discrete model is reduced with delay matrix D_k. The method is simple, saving computer time and of considerable accuracy.
