摘 要: 针对冶金机电系统存在复杂耦合关系的特点, 引用分形几何中的概念将机电系统分解为易于描述和求解的简单子系统。根据模式识别理论识别系统最有希望的可能解空间， 运用多目标决策方法对系统分形解进行合成，提出采用分解-并行-合成的设计策略和建立综合科学理论、经验知识、专家判断力的集成设计系统是机电系统解耦设计的关键。

Abstract:Aimed at the characteristic of metallurgical mechanical-electrical system which existed complex coupling problem, the authors quoted the conception of fractal to resolve mechanical-electrical system into simple subsystems, which are easy to be described and to be solved, then identified the most expectant probable solving space in the light of the model identification theory and applied the mutiple-target decision method to compose the system fractal solving. At last it was put forward that adopting the design strategy of resolving-parallel-composing and building up the integrated design system that synthesized the science theory, the experience knowledge and the expert judgment, are the key to decoupling design in mechanical-electrical system.
Key words: fractal decoupling optimization design
