| 摘 要： | 在分析基于常规QP方法来设计稳定IIR微分器而存在的苛刻的稳定性约束和代价函数不可靠两点不足的基础上，本文提出了一种新的基于IQP的稳定IIR微分器设计算法，本算法应用Rouche定理和有关的收敛准则，解决了稳定性和代价函数存在的问题，从而有效地减少了微分器的设计误差，改善了微分器的性能，使得新的设计方法更加完善、可靠。实例证明了这种设计方法的合理性、可行性，从而为它更加宽广的应用前景奠定了基础。

| Abstract: | Based on the drawback analysis of stable IIR differentiator design using conventional QP method, which is too rigorous stability restriction and no credibility of cost function for digital differentiator, a new IQP-based algorithm for stable IIR differentiator design has been presented in this paper. Using Rouche theorem and some convergence rule, we solve the problems of stability and const function, which reduces the design error effectively and improvement the performance of differentiator, so the new method is more perfect and credible. By example, the rationality and feasibility have been tested successfully, which settles the foundation for largo application foreground all the more |
