Robust Cascade Controller for Nonlinearly Actuated Biped Robots: Experimental Evaluation
(2004-06-26)
In this paper we consider the postural stability problem for nonlinearly actuated quasi-static biped robots, both with respect to the joint angular positions and also with reference to the gripping effect between the ...
Nonlinear Control Strategy based on Discrete-Time State Dependent Riccati Equation for Electronic Throttle Control
(Ieee, 2016-01-01)
This paper aims to present a new control strategy for eletronic throttle control (ETC) used for the acceleration function in a vehicle. Firstly, an analitical model describing is developed with the purpose to evaluation ...
Robust static output feedback <i>H</i><sub></sub> control for uncertain Takagi-Sugeno fuzzy systems
(2022-01-01)
In this work, a robust static output feedback (SOF) design for continuous-time nonlinear systems under norm bounded uncertainties, described as a Takagi-Sugeno (TS) system is proposed. The key features are that a switching ...
Dynamic Friction Model Study Applied to a Servomechanism at Low Velocities
(2021-01-01)
The following work contains an experimental method for identifying dynamic friction in a DC servomotor, whose identification and subsequent compensation is highly important. Friction has characteristics that are difficult ...

Mathematical modelling, nonlinear dynamics, bifurcation, synchronization and control of mechanisms driven by power supply
(2021-01-01)
The special issue entitled “Mathematical modelling, nonlinear dynamics, bifurcation, synchronization and control of mechanisms driven by power supply,” published by The European Physical Journal: Special Topics (EPJST), ...
Optimal linear control driven for piezoelectric non-linear energy harvesting on non-ideal excitation sourced
(2014-01-01)
Non-linear energy harvesting system was project to enhance interaction to ambient vibration that is wide band and low power which difficult the design for resonant solution. To improve efficiency of a non-linear design it ...
Chaos control of a nonlinear oscillator with shape memory alloy using an optimal linear control: Part I: Ideal energy source
(Springer, 2009-01-01)
In this paper, an optimal linear control is applied to control a chaotic oscillator with shape memory alloy (SMA). Asymptotic stability of the closed-loop nonlinear system is guaranteed by means of a Lyapunov function, ...
