A new method of designing observer-based deadbeat controllers for linear multivariable systems is presented. The design procedure consists in solving a linear equation in polynomial matrices and yields the entire controller, including the observer plus state feedback, in a single step. The resulting algorithm is remarkably simple, efficient, and leads to an economical realization of the control...

This paper deals with the design of a high gain observer and sliding mode controller for a remotely controlled quadrotor vertical take off and landing aircraft. Under the restriction that only the inertial coordinates and yaw angle are available for measurement, a high gain observer is designed which allows estimating on-line the roll and pitching angles as well as all the linear and angular ve...

This paper deals with a design problem of an observer-based robust preview control system for uncertain discrete-time systems. In this approach, we adopt 2-stage design scheme and we derive an observer-based robust controller with integral and preview actions such that a given performance index is satisfactorily small for uncertainties. In this paper, we show that suÆcient conditions for the ex...

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 ...

The quality of control actions depends strongly on the availability and the quality of signals to construct the controller. While most control design tools assume all states, hence signals, are measurable, this is often unrealistic. An observer is often necessary to provide signals to use in controller realization. This paper proposes the construction of a reduced order observer and an output f...

The present paper deals with a decoupled multimodel predictive control based on multi-observer for the control of discrete-time nonlinear systems with time-varying delay. For each local model, a controller based on partial predictor/observer is synthesized. A switching algorithm is established to yield the adequate partial controller ensuring the closed-loop desired performances. Simulation res...

The problem of stabilizing steady gliding is critical for an underwater glider, which is subject to many non-negligible disturbances from the aquatic environment. In this paper, we propose a new systematic controller design and implementation approach for the stabilization problem, including a nonlinear, passivity-based controller and a nonlinear model-based observer, where the actuation is rea...

In this paper, an observer-based sampled-data controller of linear system is proposed for the wave energy converter. Based on the sampled-data observer, the controller is design. In the closed-loop system with controller, it obtains the norm inequality between the continuous-time state variable and the discrete-time one. Using the norm inequality, sufficient condition is derived for the asympto...
