Optimal state derivative feedback control for singular systems
14th International Conference on Sciences and Techniques of Automatic Control & Computer Engineering - STA'2013, 2013In 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.

Discrete-time design of state-derivative feedback control laws
2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013State-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.

Robust state derivative feedback LMI-based designs for discretized systems.
Anais do Congresso Brasileiro de Automática 2020, 2020This 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

COMPARATIVE STUDY ON STATE FEEDBACK AND STATE-DERIVATIVE FEEDBACK IN LINEAR TIME INVARIANT SYSTEMS
IFAC Proceedings Volumes, 2007Abstract State feedback is a modern control technique that, amongst diverse applications, is distinguished by its arbitrary pole-placement of a controllable, linear time-invariant system. This benefit brings a series of consequences, such as the stabilization of a system or designing control using one single technique.

Pole-Placement for Multi-Input Linear Systems by State Feedback or State-Derivative Feedback
Advanced Materials Research, 2012Generalized Wonham controllable canonical forms are introduced to apply to pole placement of state feedback or state derivative feedback. New methods of pole placement of both state feedback and state derivative feedback for multi-input system are proposed.

IEEE Transactions on Power Electronics, 2004
This paper presents a novel nonlinear speed/position control strategy for the induction motor utilizing exact feedback linearization with state and state derivative feedback. The speed/position and flux control loops utilize nonlinear feedback which eliminates the need for tuning, while ordinary proportional-integral controllers are used to control the

L2gain state derivative feedback control of uncertain vehicle suspension systems
Journal of Vibration and Control, 2017This 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, 2005Abstract 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.

Pole-placement for SISO linear systems by state-derivative feedback
IEE Proceedings - Control Theory and Applications, 2004A procedure for solving the pole-placement problem for a linear single-input/single-output (SISO) systems by state-derivative feedback is described. This pole-placement problem is always solvable for controllable systems if all eigenvalues of the original system are nonzero.

Rejection and tracking sinusoidal signals based on state-derivative feedback
2015 34th Chinese Control Conference (CCC), 2015This article investigates the control problem of rejection and tracking unknown sinusoidal signals for linear timeinvariant systems. The derived controller is in terms of state-derivative feedback since the derivative of the state rather than the state can be directly measured in some cases.
