Stability impact of small delays in proportional–derivative state feedback [PDF]
Control Engineering Practice, 2009 Abstract This paper points out specific stability problems of the state derivative and proportional–derivative state feedback which may result from the presence of otherwise negligible delays in the control loops. It is shown that the stability problems arise from the neutral character of the closed-loop system with the state derivative action under ...

Relaxation oscillations in solid-state lasers with derivative feedback
Izvestiya VUZ. Applied Nonlinear Dynamics, 1998 The feedback proportional to е derivative of laser intensity can affect only the system stability without changing the system steady state. In the present work by the example of a two-mode solid-state Jaser we show the possibility to excite quasi-sinusoidal self-modulation regime using only negative feedback which is proportional in this case to the ...

Adaptive State Feedback—Theory and Application for Wind Turbine Control
Energies, 2017 A class of adaptive disturbance tracking controllers (ADTCs) is augmented with disturbance and state estimation and adaptive state feedback, in which a controller and estimator, which are designed on the basis of a lower-order model, are used to control ...

Stabilization of Linear Time-Invariant Systems by State-Derivative Feedback
WSEAS TRANSACTIONS ON SYSTEMS AND CONTROL, 2023 In this paper is studied the stabilization problem by state-derivative feedback for linear time-invariant continuous-time systems. In particular, explicit necessary and sufficient conditions are established for the stability of a closed-loop system, obtained by state-derivative feedback from the given linear time-invariant continuous-time system ...

A Direct Algorithm for Pole Placement by State-derivative Feedback for Single-input Linear Systems
Acta Polytechnica, 2003 This paper deals with the direct solution of the pole placement problem for single-input linear systems using state-derivative feedback. This pole placement problem is always solvable for any controllable systems if all eigenvalues of the original system
