Synchronization in identical drive-response systems is a problem that can be cast in an observer design framework. In this paper we extend this approach by studying the analysis/design of partial synchronization by means of observer theory. In doing so, we introduce the concept of partial observer--an observer to reconstruct a part of the system state vector. It is also shown how the observabil...

In this paper, we propose an observed-based control for the PVTOL aircraft considering that the angular position is not measurable. The control strategy presented here, is robust with respect to observer errors and takes into account constraints imposed by the nonlinear observer. The observer design is based on the assumption that the horizontal position is the only available measure. We presen...

Abstract: A robust/adaptive stochastic observer is presented for stochastic nonlinear dynamics having excessive uncertainties. It was shown through a new theorem that the proposed nonlinear robust sliding mode observer has very accurate state estimate error characteristic. The observer uses the sliding mode technique for the robustness and a deterministic adaptive law to guarantees a globally a...

This paper presents the implementation of a modified state observer-based adaptive dynamic inverse controller for the Black Kite micro aerial vehicle. The pitch and velocity adaptations are computed by the modified state observer in the presence of turbulence to simulate atmospheric conditions. This state observer uses the estimation error to generate the adaptations and, hence, is more robust ...

This paper presents the experimental results of the investigation of the effects of the observer poles for shaping the dynamic responses of state-space systems with system poles placed by state vectors obtained from full-order observers instead of the original full state vectors, which is assumed to be unavailable. The particular parameters considered in the shaping of the dynamic responses in ...

Predictive control is a strategy where the current control action is based on a prediction of the system response at some number of time steps into the future. This approach allows one to work directly with an input–output model of the system, in contrast to a state-space based approach where the state variable is involved explicitly in the controller design and implementation.A connection is p...

New rules are proposed to govern the collapse of a wave function during measurement. These rules apply with or without an observer in the system. They overcome an absurdity that was previous found when an objective state reduction is combined with an observer-based state reduction.
