摘要
针对在液压破碎锤控制和故障监控领域建立系统动态模型的需要,文章研究了基于状态空间模型的数字子空间状态空间系统辨识(N4SID)方法,并在某种新型液压破碎锤上进行了仿真实验,结论表明,该方法可以较准确地辨识新型液压破碎锤的系统模型。
It is important to establish system dynamic model for many fields,especially in the fields of control and failure of Hydraulic hammer. Numerical algorithm for subspace state space system identification（N4SID） is proposed in recent years and applied to communications. It is based on state-space model. N4SID is described in this papper. In this paper, N4SID is applied to identifying the Hydraulic hammer system. Moreover, the result shows that the algorithm is feasible.
