摘　　要：根据垃圾再生煤生产过程的工艺特点和要求,考虑到垃圾烘干系统的非线性和精确数学模型无法建立问题,开发了一种基于模糊-PI双模控制的垃圾烘干机。重点分析了模糊-PI双模控制器的特点和设计过程,说明了PI参数对系统特性的影响及其整定方法。模糊控制器设计采用分层控制的方法,克服了多变量模糊控制的"维数灾"问题。实践证明,该再生煤垃圾烘干机性能优越,达到了提高工作效率和降低能耗的目的。According to technological characteristics and requirements of the production process of rubbish-regenerated coal,and considering that the nonlinear and precise model of rubbish drying system fails to establish,a rubbish dryer was developed based on fuzzy-PI dual-mode control.The paper put emphasis on the analysis of the characteristics and design process of fuzzy-PI dual-mode controller,then illustrated effects of PI parameters on the system characteristics as well as its setting methods.The fuzzy controller was designed by hierarchical control to overcome the dimension disaster of the multi-variable fuzzy control.Application results show that the rubbish dryer has superior performance and achieves high efficiency and low energy consumption.
