Transfer Functions of Generalized Bessel Polynomials

Jose R. Martinez

摘要:

研究了广义贝塞尔多项式(GBP)的传递函数的稳定性和逼近性质。建立了GBP为Hurwitz的充分条件。证明了$e^{-s}$的Padé逼近与GBP有关.定义了一个稳定的Padé函数的无穷子集,用于逼近一个常数时滞,并研究了其逼近性质。将低通Padé函数与Budak提出的逼近函数进行了比较。Budak近似的基本限制。

英文摘要:

The stability and approximation properties of transfer functions of generalized Bessel polynomials (GBP) are investigated. Sufficient conditions are established for the GBP to be Hurwitz. It is shown that the Padé approximants of $e^{-s}$ are related to the GBP. An infinite subset of stable Padé functions useful for approximating a constant time delay is defined and its approximation properties examined. The lowpass Padé functions are compared with an approximating function suggested by Budak. Basic limitations of Budak's approximation are derived.
