摘　　要：三轴飞行仿真转台外框要求有相当宽的频带,因此用于外框的电液位置伺服系统的时滞就必须考虑,这对进一步提高系统频带有很大关系。本文针对电液伺服系统本身的参数变化及转台外框的时变负载,进一步考虑时滞,给出了其自适应模型跟随控制方案。该方法适合极点赢数大于2的系统,即具有不稳定逆系统的数字控制。仿真结果表明此方案对提高系统频带,抑制时变参数的影响有明显结果。The time-delay should be considered in designing the system of the outer axis of three-axis with high frequency bandwidth. This is important for improving the bandwidth of system further. Aimed at the electrohydraulic Servo systems with time-variaut and time-delay, a adaptive control approach is given in this paper. It is suit for the plants with excess pole r>2. The digital simulation shows that this method can obtain a satisfied effect.
