Nonlinear System Modeling Method of Using Orthonormal Function
Xiongzhu Bu · Journal of Nanjing University of Science and Technology · 2004
A nonlinear system modeling scheme was proposed. This scheme consists of three sections: a signal-independent standard orthonormal expansion,standard Wiener functional series derived from an estimate of vector probability density function, and a linear combiner of functional series. The prediction and identification performance of these nonlinear structures were examined by an example, which models a sensor according to the results of calibration.
