-
摘要: 本文用一维直接搜索法在给定的区域内能准确地搜索出根轨迹点或补根轨迹点.它可 适用于零极点或分式多项式且均带有纯时间迟延的开环传递函数,原则上不受阶次的限制.本 法的程序在袖珍机PC-1500上已满意地做出了大量的实例,高至十阶.Abstract: An one-dimensional direct area search method for effective search of root-loci and complementary root-loci points is presented in this paper. The input data of the open loop transfer function can be given as poles and zeros or coefficients of polynomials and all with dead time-delay. Theoretically the order of the transfer function is unlimited. A considerable number of examples up to 10th-order have been successfully worked out on a pocket computer PC-1500.
