一种自适应直流调速系统的工程实现研究

Implementation Research on an Adaptive D.C. Speed System

介绍了自适应模型跟随控制器的设计思想和软、硬件的实现方法,给出了具体实施步骤。以实验室xsw—1小功率直流调速系统为研究对象,经过辨识,建立参考模型;通过仿真,以系统阶跃响应的上升时间、超调量和稳态误差为性能评价指标,确定自适应规律及自适应控制器的结构和参数;在此基础上,选择以8098单片机为核心的数字控制器进行软硬件设计。运行结果表明,此系统便于实现,对被控对象的参数变化具有较强的适应能力,跟踪效果良好。

The design concept and hardware and software implementation of a reference model adaptive controller are introduced. The process is a minipower DC speed system. Through simulation,the reference model and the structure and parameters of the adaptive controller are confirmed. The digital controller with the core of 8098 SCM is designed and debugged on line. Experiments indicate that it has good control effects and better capability of adapting to the parameters variations of the process to be controlled. 
