摘　　要：针对一维磁悬浮系统,给出了改进型的变参数数字PID控制器,设计方法,设计了以C 8051高速单片机为核心的一维磁悬浮系统变参数PID控制器并进行了实验,实现了被悬浮物的稳定悬浮控制,控制误差较小,控制器具有一定的鲁棒性。This paper proposes design method for variable-parameter PID algorithm of one dimensional magnetic levitat ion system. A digital control ler for variable -parameter PID is designed with the chip C8051 as the core control component. Practical experiments are carried out for the controller. The test results show that the suspended solid can be levitated steadi ly and its control error is small. The control ler has a good performance of robustness.
