| 摘 要： | 本文提出了一种气动控制阀控制系统非线性因素（静摩擦O的补偿方法，就是根据实际情况在控制信号中加入某种额外脉冲信号。这有利于减小或消除爬行和需后现象，减小系统误差，从而改善系统的精度和稳定性。

| Abstract: | A method for compensation the static friction ( stiction ) in pneumatic control valves is presented. The compensation is obtained by adding pulses to the control signal. The characteristics of the pulses are determined from the control action. The procedure reduces the control error during stick-slip motion significantly compared to the standard control without stiction compensation. |
