摘　　要：利用伪随机信号作为系统的输入信号,对电液伺服系统进行在线辨识的方法,得出系统的数学模型,利用Hankel矩阵法确定模型的阶次,并用多步最小二乘法辨识出系统的开环传递函数。The method of pseudo-random signal as the input signals of the servo-system for on line identification is introduced in this paper.An electro-hydraulic servo-system is identified with this method and the mathematic model of the system is obtained.The rank of the model is determined by the method of Hankel matrix.
