摘　　要：本文提出了一种新的PID自整定调节器——专家自整定调节器。其自整定策略不是依赖于建立对象的数学模型,而是从过程的控制曲线出发,采用一种基于知识的推理校正方法。这种算法的搜索过程是迅速的、启发式的。仿真结果表明,初始的PID 整定值即使偏离其最佳值很远,也能被迅速地校正到最佳值上。因此,这种方法对于解决特别是时变对象的PID参数在线自整定问题,开辟了新的行之有效的途径。This paper presents a new kind of self-tuning controller——Ex-pert Self-tuning Controller using error versus time curves of a process infere-nce-adgustment strategies for its self-tuning based on knowledge instead ofbuilding the precise mathematical model of a process.The search for the optim-um (expected) PID is quick and heuristic which is also shown by simula-tions.this is obviously a new method for time-variable processes control.Anhertonew method for model recognition is also proposed that is characterized by itssimplicity and accuray even the process is noisy,which makes the algorihmtvery practical.
