The associated bilinear approximating system is assumed to be observable for any input and stabilizable by a homogeneous feedback law of degree zero. Furthermore, we discuss the case of planar systems which admit bad inputs (i.e. the ones that make bilinear systems unobservable). A separation principle for such systems is given.}, type={artykuł}, title={Separation principle for nonlinear systems: A bilinear approach}, keywords={nonlinear systems, bilinear systems, observers, stabilization}, }
