1.引言在过去二十年中作了大量努力,企图研制一种在控制下能调整其性能的调节器,以促进自动调谐方案。尽管对自动调谐的实现和使用的兴趣日益增长,理论领域的深入进展,微计算机的计算能力增加,但是,只有少量的报导涉及一般目地的控制系统。实际上,工程师们 1. INTRODUCTION Much effort has been spent in the last two decades in an attempt to develop a regulator that can adjust its performance under control to facilitate an automatic tuning scheme. Despite the increasing interest in the implementation and use of autotune, the advances in the field of theory have increased the computational power of microcomputers, but only a few reports have dealt with general purpose control systems. In fact, engineers
