改进的Butterworth最佳传递函数标准型

The Improved Standard Form of Butterworth Optimum Transfer Function

针对Butterworth最佳传递函数随着阶数增大,超调量增大,单位阶跃响应品质变差的问题,本文提出一种改进的Butterworth最佳传递函数来提高系统的瞬态响应品质,并给出改进的Butterworth最佳传递函数的标准型以及它们的单位阶跃响应。

<Abstrcat>With the increase of the order of Butterworth optimum transfer function, its overshoot is also increased and its step response quality is reduced. So the improved Butterworth optimum transfer function ,which increases the transitional response quality of the control system, is presented in this paper. At last, the standard form and the unit step response of the improved Butterworth optimum transfer function are also given.
