摘　　要：IIR数字滤波器设计的本质是求解多参数非线性复杂函数优化问题,提出应用实数编码量子进化算法优化IIR数字滤波器的相关参数,进而形成一种新的IIR数字滤波器优化设计方法。文中给出了IIR滤波器优化设计的数学模型,描述了应用实数编码量子进化算法优化设计IIR数字滤波器的具体实现步骤,并通过低通和高通IIR数字滤波器设计的仿真结果表明该方法的有效性和高效性。Based on optimization design for IIR digital filters being a multi-parameters and non-linear complex function optimization problem, a novel method of IIR digital filters optimization design is proposed, its core is that read-coded quantum evolutionary algorithms（RQEA）is applied on optimizing the interrelated parameters of IIR digital filters.In this paper, firstly, the maths model of IIR digital filter optimization design is proposed; secondly, the process of optimization design for IIR digital filters on the basis of RQEA is described in detail, finally, the validity and effectivenss of the introduced method are demonstrated by experimental results on the lowpass and highpass IIR digital filters.
