高精度伺服系统基于Fuzzy决策的专家变模态控制

THE MULTISTAGE EXPERT CONTROL OF HIGH PRECISION SERVO SYSTEM BASED ON FUZZY DECISION

本文简要回顾了具有双积分模型的电流驱动直流机电伺服系统的传统设计方法，设计了基于Ｆｕｚｚｙ决策的专家变模态控制器。该控制器积累了伺服系统设计的一些经验，具有一定的“社会智能”，可以在系统运行的不同阶段自发地选用合适的控制律，组合简单的控制方法实现高品质控制。体现了将控制任务分解成子任务分阶段完成的思想。

The paper had briefly recalled the classical design theory of servo system for DC motor which had dual-integration model, and had designed the MEC(Multistage Expert Controller). The controller had gathered all the experience in the design of servo system.It also had some ability so called as 'social intelligence', so it could automatically figure out the certain control method in many states of the system,and it had made the system have high quality by the combination of several single controllers, so it had completed the control task by completing each of the submissions.
