Optimal state derivative feedback control for singular systems

14th International Conference on Sciences and Techniques of Automatic Control & Computer Engineering - STA'2013, 2013
In this paper, a linear quadratic optimal control problem for linear descriptor systems is investigated. The optimal control is synthesized as derivative state feedback which guarantees that the closed loop system is stable and that minimizes quadratic criteria expressed a performance level.

Regularization of Descriptor Systems by Derivative and Proportional State Feedback

SIAM Journal on Matrix Analysis and Applications, 1992
Summary: For linear multivariable time-invariant continuous or discrete-time singular systems it is customary to use a proportional feedback control in order to achieve a desired closed loop behaviour. Derivative-feedback is rarely considered. This paper examines how derivative feedback in descriptor systems can be used to alter the structure of the ...

Feedback control of singular systems—proportional and derivative feedback of the state

International Journal of Systems Science, 1983
This paper examines the use of proportional and derivative feedback of the state as a means of regularizing and controlling singular systems. Regularizability is defined as the existence of a derivative feedback control law such that the closed-loop system is regular.

Bond graph approach for disturbance rejection with Derivative State Feedback

Proceedings of the 11th International Conference on Integrated Modeling and Analysis in Applied Control and Automation (IMAACA 2018), 2018
"This paper presents the application to a real Torsion-Bar system of Disturbance Rejection by Derivative State Feedback using an Unknown Input Observer. Finite and infinite structures of the model are analysed with a structural approach directly on the bond graph model and thus properties of the controlled system as well as the observer are ...

Discrete-time design of state-derivative feedback control laws

2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013
State-derivative feedback control laws can be very useful in the control of systems using accelerometers as sensors. Moreover, in cases where both state and state derivative measurements are available, a state-derivative feedback controller can be employed as a backup alternative in the case of sensor failure.

Proportional and derivative state-feedback decoupling of linear systems

IEEE Transactions on Automatic Control, 2000
Consider the standard linear system \(\dot x(t)= Ax(t)+ Bu(t)\), \(y(t)= Cx(t)\). The proportional and derivative state feedfack decoupling problem for this system is to design a control of the form \(u(t)= F_d\dot x(t)+ F_p x(t)+ r(t)\) such that the output \(y\) of the closed loop system is identical to \(r\).

Robust state derivative feedback LMI-based designs for discretized systems.

Anais do Congresso Brasileiro de Automática 2020, 2020
This work addresses novel Linear Matrix Inequality (LMI)-based conditions for thedesign of discrete-time state derivative feedback controllers. The main contribution of this work consists of an augmented discretized model formulated in terms of the state derivative, such that uncertain sampling periods and parametric uncertainties in polytopic form can

L₂gain state derivative feedback control of uncertain vehicle suspension systems

Journal of Vibration and Control, 2017
This paper is concerned with the design of a robust L2gain state derivative feedback controller for an active suspension system. An uncertain quarter vehicle model is used to analyze vehicle suspension performance. Parametric uncertainty is assumed to exist in sprung mass, tire stiffness and suspension damping coefficients.

STATE DERIVATIVE FEEDBACK BY LQR FOR LINEAR TIME-INVARIANT SYSTEMS

IFAC Proceedings Volumes, 2005
Abstract In this paper, state-derivative and especially output-derivative feedbacks for linear time-invariant systems are derived using control approach similar to linear quadratic regulator (LQR). The optimal feedback gain matrices are derived for the desired performance.

Positive stabilization of singular systems by proportional derivative state feedback

2017 IEEE Conference on Control Technology and Applications (CCTA), 2017
This paper considers the problem of positive stabilization of linear continuous-time singular systems by both proportional and proportional derivative state feedback. First, we provide conditions for a singular system to be admissible (stable, regular, and impulse-free).
