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 ...
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 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, ...
Robust state-derivative feedback LMI-based designs for multivariable linear systems
(Taylor & Francis Ltd, 2007-08-01)
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. New necessary and sufficient ...
Robust State-Derivative Feedback LMI-Based Designs for Linear Descriptor Systems
(Hindawi Publishing Corporation, 2010-01-01)
Techniques for stabilization of linear descriptor systems by state-derivative feedback are proposed. The methods are based on Linear Matrix Inequalities (LMIs) and assume that the plant is a controllable system with poles ...
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 ...
Dynamic output feedback control of switched linear systems
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2008)
Proportional controllers: Direct method for stability analysis and MATLAB implementation
(Institute of Electrical and Electronics Engineers (IEEE), 2007-02-01)
In most cases, the cost of a control system increases based on its complexity. Proportional (P) controller is the simplest and most intuitive structure for the implementation of linear control systems. The difficulty to ...
On switched control design of linear time-invariant systems with polytopic uncertainties
(2013-05-27)
This paper proposes a new switched control design method for some classes of linear time-invariant systems with polytopic uncertainties. This method uses a quadratic Lyapunov function to design the feedback controller gains ...
Learning climate and feedback as predictors of dental students' self determined motivation: the mediating role of basic psychological needs satisfaction
(Wiley, 2018)
AimThe aim of this study was to test the mediating role of the satisfaction of dental students' basic psychological needs of autonomy, competence and relatedness on the association between learning climate, feedback and ...
