模糊PID控制在伺服控制器中的应用

摘要

The paper aims at the defect of common PID control er,we design self-adapted fuzzy PID control er.we use fuzzy rules to modify the PID parameters online with the aim of getting along with the parameter and work condition changes of subjects.The result shows the digital servo system has good dynamic and static performance,quick dynamic response, good versatility,reliable work,strong robustness,and meet to system control target.Key words:Fuzzy-PID-control;adaptive;servo-control er%　　本文针对常规PID控制器的缺点，设计了模糊自适应PID控制器，利用模糊规则在线对PID参数进行修正，以适应被控对象的参数变化和工作条件的变化。该数字伺服控制器具有良好的动静态性能，动态响应快，通用性好，工作可靠。满足系统控制指标，具有较强的鲁棒性。
