引言随着科学和技术的飞跃发展,生产过程和设备的日益完善,调节对象的动力学以及它在结构设计和自动调节系统中的应用,目前已逐渐形成一门学科。为了今后讨论和确定这门学科应有的地位,本文准备就最近十多年来有关热工调节对象动态特性方面的文献进行综述。一、研究对象动力学的目的根据对象的动态特性可以正确合理地选择调节方案和设计调节系统,例如,设计一个自治调节系统(或不相关调节系统)时,必须准确了解调节对象的动态特性及其数学描述,因为自治调节系统的结构完全取决于对象的特性。以往经验证明,在复杂对象的调节中,许多失败都是由于对对象特性估计得不够正确所引起。为了迅速和及时地投入调节系统,并保证系统在最佳和可靠的条件下工作,必须根据对象动态特性,正确地整定调节系统的参数。研究对象动力学也是改进现有调节系统存在问题的一个有效途径。
INTRODUCTION With the rapid development of science and technology, the production process and equipment have been improved day by day, the dynamics of the object of adjustment and its application in structural design and automatic adjustment system have gradually formed a discipline. In order to discuss and determine the proper position of this discipline in the future, this article is going to review the literature on the dynamic characteristics of thermal-controlled objects in recent ten years. First, the purpose of research object dynamics According to the dynamic characteristics of the object can correctly and rationally select the adjustment program and design adjustment system, for example, the design of an autonomous adjustment system (or irrelevant adjustment system), you must accurately understand the dynamic characteristics of the adjustment object and Its mathematical description, because the structure of autonomous regulatory system completely depends on the characteristics of the object. Past experience shows that in the adjustment of complex objects, many failures are caused by the incorrect estimation of object characteristics. In order to quickly and timely control system into place, and to ensure that the system works in the best and reliable conditions, the parameters of the control system must be set correctly according to the dynamic characteristics of the object. Research object kinetics is also an effective way to improve the existing regulatory system.
