新型高阶Butterworth最佳传递函数

Study of the New High Order Butterworth Optimum Transfer Function

提出一种新型高阶Butterworth最佳传递函数的设计方法,给出其频率特性和单位阶跃响应．实例和仿真都表明,新型高阶Butterworth最佳传递函数优于传统高阶Butterworth最佳传递函数,既降低系统的超调量,又提高系统的鲁棒性．

In this paper, a method of designing a new high order Butterworth optimum transfer function is presented, the new high order Butterworth optimum transfer functions as well as their frequency characteristics and unit step responses are also given. The example and simulation show that the new high order Butterworth optimum transfer functions are su- perior to the traditional high order Butterworth optimum transfer functions, which can reduce the overshoot of the system and increase the robustness of the system.
