摘要
探讨应用四阶龙格-库塔法进行电机数字仿真时常遇到的有关问题,包括对电机方程组病态性的判断和仿真时最佳步长的确定等,实践证明,应用本文提出的判据和方法,可使电机的数字仿真得到快速、准确的效果。
In applying the 4th Runge-Kutta method to digital simulation in motor, two problems are presented:1) the method is unfit for some system of ill-condition difference equation of motor; 2) the best step in simulation must be calculated in advance when the method is used.How to determine the fit condition and the best step for this method is investigated.The results show that the criterion and the method proposed in this paper are effecient and accurate.
