This paper presents a solution for the design of a time-varying and parametric output feedback controller for known general nonlinear dynamic systems subjected to linear output structure. The controller consists of tw...

For a system in observer canonical form, observerdesign is straightforward. The resulting observer has linear error dynamics. In general, the required change of coordinates is difficult to compute. These difficulties...

nonlinear descriptor systems are considered which are gouvemed by linear differential-algebraic equations superposed by additional nonlinear effects. Based on the method of disturbance observers a generalized linear o...

The paper studies possible connections between non-linear observerdesign as introduced in Automatic control Theory and filter design as established in Signal Processing. It is shown in the paper that there are obviou...

In this paper, we introduce an extended quadratic transformation to put Single-Input Single-Output (SISO) systems in particular observer forms. This new type of quadratic transformation takes into account input-output...

In their recent work, Wang et al. proposed an interesting technique for generating chaos in Chua's circuit via time-delay feedback (Wang et al., 2001). For this class of nonlinear dynamical systems, we provide in ...

Friction may be a major obstacle for stability and control performance. Based on a nominal control law, which stabilizes a nonlinear dynamical system to an equilibrium or to a desired limit cycle motion and which is d...

This contribution extends Tecent results on flatness-based feedback tracking control based on formal power series for nonlinear diffusion-convectionreaction systems (DCRS). Thereby, a suitable summation method is intr...
