Abstract

Received Apr 23, 2019 Revised Jul 5, 2019 Accepted Oct 6, 2019 In this paper, an identification method is proposed to determine the nonlinear systems parameters. The proposed nonlinear systems can be described by Wiener systems. This structure of models consists of series of linear dynamic element and a nonlinearity block. Both the linear and nonlinear parts are nonparametric. In particular, the linear subsystem of structure entirely unknown. The considered nonlinearity function is of hard type. This latter can have a dead zone or with preload. These nonlinear systems have been confirmed by several practical applications. The suggested approach involves easily generated excitation signals.
非线性系统参数的估计
本文提出了一种非线性系统参数的辨识方法。所提出的非线性系统可以用维纳系统来描述。该模型结构由一系列线性动力单元和非线性块组成。线性部分和非线性部分都是非参数的。特别是线性子系统的结构完全未知。所考虑的非线性函数是硬型的。后者可以有一个死区或预加载。这些非线性系统已被几个实际应用所证实。建议的方法包括容易产生的激励信号。
