摘　　要：本文提出了一种在线辨识别线性多变量系统状态空间数学模型——SSMM-State-Space Mathematical Model的新方法.该法将系统辨识理论与微机应用相结合,实现了由微机完成全部辨识过程.应用本法在一台外圆磨床上作了试验,得到了良好的结果.文中详细陈述了在线辨识公式的推导,系统阶次的估计,规范化实现的求取和模型的有效性检验.A new method on-line identification of the state-space mathematical model of linear multivariable systems is proposed in this paper. It combines the theory of system identification with the application of micro-computer. So, a set of identifying procedures done by a computer has deen realized. A test of the application has been done on a cylindrical grinder and the results are desirable. The online identification formulate deduction, the system's order estimation, the canonical realization computation and the model validation check are described in detail in the paper.
