负载模拟系统始终受到舵机运动的干扰和工程噪声的影响,因此需要有效的方法消除这些干扰对系统辨识的影响,为提高辨识结果准确性,提出了基于M序列的广义最小二乘参数估计算法,并设计了基于PC的实验方法和应用程序。仿真结果与实验结果表明该方法是有效和准确的。

Load simulation system is always interfered by rudder movement and engineering noise, so it is necessary to eliminate the interferences which affect the accuracy of system identification. An M sequence based generalized least square estimation algorithm was proposed for accuracy improvement, and an experimental method and an application program were designed based on PC. The experiment results of test and simulation show that this identification method is feasible and accurate.
