摘　　要：本文在伪微分反馈控制的基础上,提出了一种分数阶伪微分反馈控制的思想,解决了整数阶伪微分反馈控制中保证系统控制性能和提高系统稳定裕度之间矛盾的问题。并将该控制算法应用于某型机载光电陀螺稳定平台。实验结果表明,该控制算法和经典的PID控制相比,能够有效地抑制力矩扰动,且对被控对象的模型摄动有较强的鲁棒性。同时,该算法还具有简单易于工程实现的优点。In this paper, pseudo-derivative feedback control is proposed based on a pseudo-differential fractional feedback control theory. The control algorithm can not only improve the system performance but also guarantee the stability margin, that the integer-order pseudo-differential control feedback control can not be achieved. And the control algorithm is applied to a certain type of airborne photoelectric gyro stabilized platform. Experimental results show that the algorithm proposed can suppress torque disturbance effectively, also is not sensitive to the model variety compared with classical PID control. Meanwhile, the algorithm is simple to be applied to the real system.
