Abstract :
This paper deals with quadratic observability normal form for nonlinear single output system. A linearly observable case is first investigated and after one dimensional linearly unobservable case is studied. More particularly, the effect of the so-called resonant terms on the observer design is point out. Throughout the paper, some academic examples as well as bio reactor example highlight our purpose
