摘　　要：针对负压伺服控制系统特点，提出采用模糊ＰＩ复合控制器补偿系统弱品质，实现了负压气信号的高精度、高响应的实时控制．实验研究表明，这种负压伺服控制系统具有良好的稳态精度和动态性能，如跟踪频率为ｆ＝ ０．６ Ｈｚ 的正弦波时，其幅频误差和相频误差分别为０．３６ ％ 和３．５９４ ９°，所产生的负压气信号能够满足某仿真装置的精度和响应特性的要求．According to the characteristics of the vacuum servo system, the idea that a FUZZY controller combined with PID control compensates the poor characteristics of the vacuum servo system is presented. The continuous control of high accuracy and fast response for the system is implemented. The experimental studies show that the system has excellent steady error and dynamic characteristics, e.g. the errors of amplitude and phase are 0.36% and 3.5949° respectively when tracing sinwave signal (frequency is 0.6Hz). The vacuum air signal obtained is satisfied for the accuracy and responsive characteristics of the simulated equipment.
