Kinematic nonlinear controller for a miniature helicopter via Lyapunov techniques
(Wiley, 2014-05)
This work proposes a kinematic nonlinear controller for an autonomous miniature helicopter that generates saturated reference velocity commands for accurate waypoint trajectory tracking. The control law design is based on ...
Fixed-point DSP implementation of nonlinear H(infinity) controller for large gap electromagnetic suspension system
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Electromagnetic suspension systems are inherently nonlinear and often face hardware limitation when digitally controlled. The main contributions of this paper are: the design of a nonlinear H(infinity) controller. including ...
On nonlinear dynamics and control of a robotic arm with chaos
(E D P Sciences, 2014-01-01)
In this paper a robotic arm is modelled by a double pendulum excited in its base by a DC motor of limited power via crank mechanism and elastic connector. In the mathematical model, a chaotic motion was identified, for a ...
Remarks on an Optimal Linear Control Design Applied to a Nonideal and an Ideal Structure Coupled to an Essentially Nonlinear Oscillator
(Asme-amer Soc Mechanical Eng, 2013)
A comparative study between two relaxed LMI-based fuzzy control designs
(2005-09-01)
A comparative study, with theoretical analysis and digital simulations, of two conditions based on LMI for the quadratic stability of nonlinear continuous-time dynamic systems, described by Takagi-Sugeno fuzzy models, are ...

Parametric uncertainty and disturbance attenuation in the suboptimal control of a non-linear electrochemical process
(John Wiley & Sons Ltd, 2007-12)
The optimal control of the hydrogen evolution reactions is attempted for the regulation and change of setpoint problems, taking into account that model parameters are uncertain and I/O signals are corrupted by noise. ...
Nonlinear Control of a Buck Converter Feeding a Constant Power Load
(Institute Of Electrical And Electronics Engineers, 2014-08)
In this paper a nonlinear control strategy for controlling a dc/dc Buck converter feeding a constant power load is proposed. A feedback controller is combined with a feedforward strategy. A nonlinear reduced order observer ...
Characterization of grazing bifurcation in airfoils with control surface freeplay nonlinearity
(European Assoc Structural Dynamics, 2014-01-01)
A variety of nonlinear features is obtained from aeroelastic systems with discontinuous nonlinearity motivates investigations that may support future applications in controls design, flutter prediction problems, and energy ...
