A computer-aided method for linear discrete-time system model reduction via step-response matching is presented in this paper . Golub's algorithm for solving least squares problem is used to find the optimun coefficients of the reduced model. The advantage of this method is that both the time response and frequency response within the bandwidth region of reduced model are very close to that of original model.Several illustrative examples are provided.

一般而言，數值控制工具機切削路徑之決定，頗為複雜，人工設計費時，宜改採用計算機輔助設計；本文提供一種簡潔設計方法，首先將二維空間的物面結構分為五種，經由此五種物面的組合可得任何一種較複雜之物面。文中提供計算機輔助設計之技巧，以達成物面切削之全面自動化設計，而縮短設計時間。其所需之記憶空間不必很大。
