In the recent literature, some practical systems have been modeled as interval systems. In this investigation, an improved approximation technique is first proposed for model reduction in single-input-single-output continuous interval systems; then, the proposed technique is extended to reduce multi-input-multi-output continuous interval systems. The proposed technique is based on a multipoint Padé approximation. Additionally, the technique generates a stable model for a given stable system. The results show that the Routh table integrated multipoint Padé approximation is a good way to reduce continuous interval systems.

改进 SISO 和 MIMO 连续间隔系统的近似，确保稳定性

在最近的文献中，一些实际系统被建模为区间系统。在这项研究中，首先提出了一种改进的近似技术，用于单输入单输出连续区间系统的模型约简；然后，将所提出的技术扩展到减少多输入多输出连续间隔系统。所提出的技术基于多点 Padé 近似。此外，该技术为给定的稳定系统生成稳定模型。结果表明，Routh 表集成的多点Padé 近似是一种减少连续区间系统的好方法。
