【摘要】 噪声存在时,模型结构难以精确辨识,因此就不易获得与系统代数等价的模型。本文的讨论表明,可以用脉冲传递函数等价的模型描述系统。并以简例说明了用有限的马尔可夫参数实现状态模型和差分模型的统一方法。更多还原

【Abstract】 In noisy Case, the model structure can not be exactly identified, and it is defficult to obtain the state space model in algebraic equivalence. For this reason, we suggest the model based on impulse transfer function eguivalence to describe the system. Simple examples for explaining the unifying realization methods of state space and difference equation model using finite markov parameters are also presented in this paper.更多还原
