This paper studies the design of a model following control system (MFCS) for nonlinear descriptor system in discrete time. In previous studies, a method of nonlinear model following control system with disturbances was proposed by Okubo,S. and also a nonlinear model following control system with unstable zero of the linear part, a nonlinear model following control system with containing inputs ...

This report treats some basics on parameter identification in linear time invariant descriptor systems, both time continuous and time discrete. It is shown how identification methods for normal state space systems can be used by transforming the descriptor system to state space form. It is also examined how identification can be performed in the frequency domain.

A common method to determine the order of minimal realization of a continuous linear time invariant descriptor system is to decompose it into slow and fast subsystems using the Weierstrass canonical form. The Weierstrass decomposition should be avoided because it is generally an ill-conditioned problem that requires many complex calculations especially for high-dimensional systems. The present ...
