摘要
机载监视系统是现代航空领域很重要的一个研究内容,通过它可以实时观察记录飞机的多项信息,主要对监视系统的伺服控制单元进行了研究设计。因受飞机姿态变化、空中风阻力、机械振动、负载扰动、观测噪声等因素影响,导致电机旋转不稳,成像仪随之不稳,造成显示屏画面抖动,影响扫描监视效果。考虑实际应用中常规PID控制器对电机控制的局限性,提出了在PID控制算法上加入卡尔曼滤波,改进伺服控制效果。结果表明:新的控制方法对干扰有抑制作用,控制效果明显改善。
Airborne surveillance system is an important research in the field of aviation,through which a number of flight information can be real-time observed and recorded.The servo control unit of surveillance system has been studied in it.Impact factors such as changes in aircraft attitude,air wind resis-tance,vibration,load disturbance,measurement noise.etc.may cause the instability of motor rotating,imager as well as display judder.Furthermore,the affects of scanning and monitoring is impacted.Taking the limita-tions of conventional PID into consideration,the control algorithm of Kalman filter has been proposed to im-prove servo control performance.The results show that the new control method may suppress the disturbance and improve the control effect notably.
