摘要
考虑时变系统辨识中辨识设计变量的最优化问题。时变系统的参数由随机游动过程描述 ,讨论时变系统的FIR模型传递函数估计的均方误差 (MSE) ,记作MSE ,在新的准则函数极小的意义下 。
In this article the optimization problem of time varying system identification is discussed.The time varying system is described as a FIR model where the parameters modelled as random move process.The mean square error of transfer function estimations for time varying FIR model is denoted as MSE.In this article new frequency function will be minimized to solve time varying system identification of design variables for frequency region.
