✦ Synopsis

The bilinear mapping method is very important in designing digital filters from analogue filters for linear systems, because it provides a very simple conversion from a continuous system to a discrete system without introducing aliasing problems. The use of the bilinear mapping method for non-linear systems is investigated by applying it to a simple non-linear ordinary differential system. The results show that the bilinear mapping method is very stable compared to the fourth-order Runge-Kutta method and could be used for non-linear digital filter design.

Perhaps all natural and physical systems are governed by non-linear laws of nature. The dynamics of most of such systems can be mathematically represented by non-linear di!erential or integral equations, which can be studied by analytical or numerical techniques. These techniques, in many instances,

A robust identification technique is presented which extracts the linear frequency response kernel from an input/response measurement of a general non-linear system. Also the number and significance of higher order frequency response kernels required for a complete identification may be assessed fro

A bilinear model is introduced to study the effects of anti-tumor drugs on the kinetics of the cell cycle. Optimal control theory is applied in the estimation of these timevarying effects based on a least squares fit of laboratory data. This methodology enables the authors to quantify the effects of
