【摘要】 本文给出了一种计算状态转移矩阵e^At的新算法。由于应用了多项式,因此导出的新算式几乎就是e^At在区间[a,b]内的最佳逼近有理分式,文中同时给出了二阶系统的仿真结果。更多还原

【Abstract】 A new method is given in this paper for calaulating the state transition matrix eAt. Owing to the application of chebyshev polynomial, all new expressions derived are almost the optimal approximate rational fractions for which eAt is on region [a,b]. Simulation results of second order systems are also given.更多还原
