摘要
从滤波器的角度,采用IIR型滤波器对控制信号进行分数阶近似运算,详细介绍了由Simp-son积分算法和Tustin积分算法插值倒置后得到的二阶滤波器算法,并给出仿真实例验证其有效性。
Chosing the IIR- type filter control signal to fractional order approxima eration, particularly, introducing the second IIR- filter form by the stable inversion weighted sum of Simpson integration rule for the tion opIIR- order of and trapezoidal integration rule, as well as giving simulation examples to testify its validity. the the simulation examples to testify its validity.
