Direct Design of Controllers Using Complementary State and State-Derivative Feedback
(2019-04-15)
This paper is concerned with controllers design using complementary state and state-derivative feedback, as an extension of the work presented in Rossi et al. (in: Proceedings of XXI Congresso Brasileiro de Automática, ...
New less conservative methods of robust controllers design using state derivative feedback
(2018-01-01)
This paper proposes new less conservative methods for the design of robust state derivative feedback controllers in order to provide stability and improved dynamic performance to uncertain linear time invariant (LTI) ...
Estabilização de sistemas fuzzy T-S incertos usando realimenta̧ão derivativa
(2011-05-01)
In some practical problems, for instance, in the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. Thus, a method for state-derivative feedback design ...
New Design of Robust LQR-State Derivative Controllers via LMIs
(2018-01-01)
The resolution of linear quadratic regulator's problem (LQR) approached via linear matrix inequalities (LMIs) for linear and time-invariant systems is proposed in this work. The design of the controllers is based on the ...
Parameter-dependent Lyapunov functions for state-derivative feedback control in polytopic linear systems
(Taylor & Francis Ltd, 2011-01-01)
In some practical problems, for instance, the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. Using Linear Matrix Inequalities (LMIs), and applying ...
Robust state-derivative pole placement LMI-based designs for linear systems
(Taylor & Francis Ltd, 2009-01-01)
In some practical problems, for instance in the control systems for the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. Necessary and sufficient ...
Less Conservative Control Design for Linear Systems with Polytopic Uncertainties via State-Derivative Feedback
(Hindawi Publishing Corporation, 2012-01-01)
The motivation for the use of state-derivative feedback instead of conventional state feedback is due to its easy implementation in some mechanical applications, for example, in vibration control of mechanical systems, ...
Stabilizability and Disturbance Rejection with State-Derivative Feedback
(Hindawi Publishing Corporation, 2010-01-01)
In some practical problems, for instance in the control of mechanical systems using accelerometers as sensors, it is easier to obtain the state-derivative signals than the state signals. This paper shows that (i) linear ...
Less conservative conditions for robust LQR-state-derivative controller design: an LMI approach
(Taylor & Francis Ltd, 2021-03-02)
This study proposes less conservative conditions for robust linear quadratic regulator controllers using state-derivative feedback (SDF). The algebraic Ricatti equation was formulated using the SDF, and its solution was ...
Derivative Feedback Control for a Class of Uncertain Linear Systems Subject to Actuator Saturation
(2019-08-15)
This manuscript considers a class of linear systems with time-invariant uncertainties, where only the derivative of the state vector is considered for feedback. In this scenario, the proposed strategy uses auxiliary dynamics, ...
