复杂装备模糊配置的反馈式解耦设计

Feedback decoupling design of fuzzy configuration of complex equipment

针对模糊配置设计中的耦合问题,提出一种反馈式解耦的设计方法.该方法将模糊配置设计划分为用户域、功能域、物理域和过程域.其中,功能域向物理域的映射过程可通过相对增益矩阵进行表达,不同形式的相对增益矩阵描述不同的模糊配置设计,包括理想设计、解耦设计和耦合设计.对于耦合设计,构建由多粒度结构组成的过程域,多粒度结构用于结构变异.过程域作为耦合设计的反馈补偿域,通过调节功能需要与设计参数之间的相对增益矩阵实现模糊配置的反馈式解耦设计.结合企业实例,将反馈式解耦设计应用在精密塑料注射成型装备的模糊配置过程中,从而实现复杂装备的快速响应设计.

A new method of feedback decoupling design was proposed to resolve the coupling issues of fuzzy configuration design.The fuzzy configuration design is divided into customer domain,functional domain,physical domain,and process domain.Among them,functional domain is mapped to physical domain by the relative gain matrix.Different forms of the relative gain matrix describe different configuration designs,including idealized design,decoupling design and coupling design.In view of the coupling design of fuzzy configuration,the process domain is built,including multi-granularity structures for the variation.The process domain is considered as feedback compensation of coupling design,where the relative gain matrix is adjusted by the structural variation,to realize the feedback decoupling design of fuzzy configuration.Finally,the method was verified in the fuzzy configuration design of a precision plastic injection molding equipment to achieve the fast response of design of complex equipment.
