基于Hankel矩阵的天线伺服系统辨识

Identification of the antenna based on hankel matrix method

天线是一个时变、非线性、复杂的动力学系统,直接建模困难较大,通常采用系统辨识的方法得到天线模型。采用伪随机序列作为辨识输入,通过解算Makov参数得到Hankel矩阵,确定模型阶次,获取天线的状态方程。对比天线模型和实际系统的响应,辨识模型准确度较高,满足工程应用的需求。

Antenna of SATCOM on the move is an time-varying,nonlinear,complex kinetics system,directly modeling is difficult,obtain antenna model is obtained by identification generally.Adopt pseudorandom sequences as input,compute Makov parameter and the Hankel Matrix,confirm the order of the system,compute the model parameters.Comparing the response of the identifiction model and the real system,the identification model has high accuracy,meet the requirements of engineering.
