Application of Hankel Matrix Identification Method in Antenna Servo System

与经典控制理论方法相比,采用现代控制方案提高天线伺服系统的控制性能,对系统辨识精度提出了更高的要求。介绍了一种基于Markov系数的Hankel矩阵辨识法,并以实际系统为例验证了辨识效果。实验结果表明,此种方法对大口径天线伺服系统能够实现精确辨识,可以消除测量噪声对辨识的影响,并且能够精确地确定原始系统的阶次。

When using modern control scheme to improve the performance of the antenna servo control system, more rigorous standards for identification accuracy are proposed. The Hankel matrix identification method based on Markov coefficients is introduced, and an example is given to verify the actual identification performance. Experimental results show that using this method for large diameter antenna servo system can acquire a precise model, and eliminate the influence coursed by measurement noise. What＇s more, it could precisely determine the order of the original system.
