Time domain identification of non-linear systems

A new method of non-linear system design, and non-linear subsystem modelling is presented. The method is based on identifying a non-linear model for each subsystem and combining the individual models to solve the entire system. Time domain modelling and simulation is used throughout the procedure but frequency domain characteristics are also available. Modelling of non-linear subsystem is achieved by time domain measurement which offers considerable saving in measurement time. The identified models are not based on equivalent circuits and this offers flexibility and saving in the amount of data stored for each model
