摘要
为便于分析和综合电网络 ,需要将其动力学方程通过坐标变换 ,化为标准型。本文讨论了坐标变换的物理意义及其对动态特性的影响。变换后的动力学方程必须具有与原方程完全相同的传递函数 (阵 )与特征多项式以及能控性、能观性。本文还说明了如何通过坐标变换将原来方程化为所需的形式的方法。最后 。
The dynamic equations of electric network may be transformed into the canonical form by the coordinate transformation for the convinence in anylysis and synthesis of the electrical networks. This paper discusses the physical meaning of coordinate transformation and its influence upon the dynamic behaviour of electrical circuits. Under a change of coordinate the new dynamic equations must have the same transfer function(matrix) and characteristic polynomials, and the same controllability and obsevability as original ones. This paper describes the method of transforming from original equations to desired forms by coordinate transformation techniques. At last it deals with the choice of electrical parameters based on the concepts of system theory.
