Based on analysing the respective characteristics of regular PID controller in trational control theory and fuzzy logical controller in intelligent control theory, the idea and technique of expert system is introduced to develop a novel kind of hybrid intelligent controller. It can coordinate two kinds of control algorithms and tune the control parameters on-line for different working zones of the controlled process.(3) The hybrid knowledge expression model, which combines discrete state space model, fuzzy relational model and rule base model, is proposed based on analysing the characteristics of all kinds of knowledge expression models. The knowledge of the controlled process in different aspects can be expressed resonably by it. Based on the model mentioned above, the related optimization strategy for complex system is developed.

本文的主要贡献体现在：（1）以炼油厂的催化裂化装置和钢铁联合企业的大型焦炉装置两个典型的复杂工业过程为例，分析了工业大系统的许多不易控制的特性，并归纳了其中的几个典型特征；（2）针对经典控制理论中的常规PID调节器和智能控制技术中的模糊逻辑控制器各自的特点，通过引入专家系统的思想和方法，开发了一类混合式专家控制器，它同时具备在线协调两种不同控制规律和自动学习控制规则的能力；（3）通过分析各种知识表达模型的特点，提出了一类包括离散状态空间模型、模糊关系模型和规则基模型在内的混合知识表达模型，它能对过程知识在各个不同侧面给予合理的描述。
