In this paper, adaptive predictive control is proposed to control a Shape Memory Alloy (SMA) linear displacement actuator. A Black-Box (BB) model based on a Laguerre filter is used to identify the SMA actuator and the controller in closed loop. This identification is performed online using a recursive least squares (RLS) algorithm, thus providing a ...

2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, 2010
This paper dealed with position control problems of a DC motor servo system that had nonlinear friction and was subject to parametric uncertainties, external disturbances, etc.. In order to overcame those unfavourable factors mentioned above, a model reference adaptive control method was proposed to regulate the important and main speed loop in the ...

A Cubic-modification law for robust Model Reference Adaptive Control (MRAC) systems
1991 American Control Conference, 1991Robust Deterministic Model Reference Adaptive Control (DMRAC) systems aim at controlling a plant with unknown parameters in the face of disturbances and/or unmodeled dynamics. Our analysis of the dynamics generated by the so-called ?-modification and e 1 -modification laws has revealed the rich dynamics inherent in such DMRAC systems.

This paper presents the performance of proportional-integral-derivative (PID) controller and Model Reference Adaptive Controller (MRAC) on regulating essential oil extraction process. The quality of essential oil will reduce if the extraction process expose to overheating of temperature.

1992
Model reference adaptive control of a robotic manipulator using a modified output error method is introduced. In the absence of nonlinearities in an integrated dynamical model of a manipulator and actuators, the defined new regressors and augmented error in the modified output error method result a closed-loop system that is globally asymptotically ...

2020 IEEE International Conference on Power Electronics, Smart Grid and Renewable Energy (PESGRE2020), 2020
Microgrids (MG) are considered as a potential factor while focusing on a reliable supply and flexible control capabilities at the distribution side. These are broadly classified by two types, the grid supported or the grid connected and, the islanded or isolated type.

1993 American Control Conference, 1993
The I/O VS-MRAC redesign and stability analysis presented earlier for the case of plants with relative degree n* ? 2 (ACC'92), is generalized to the case of arbitrary n*. The redesign is based on the explicit consideration of input disturbances which, in addition to actual external disturbances, may include the disturbance originated by the uncertainty

1992 American Control Conference, 1992
Redesign and stability analysis of I/O VS-MRAC systems are presented. The key novel idea is to consider the effect of the uncertainty on the plant "high-frequency gain" (HFG) as an input disturbance acting on a plant with known (nominal) HFG. This leads to redesign and substantial simplification of the stability analysis, under less restrictive ...

Proceedings of the 27th IEEE Conference on Decision and Control, 2003
For pt.I. see Tech. Rep. RT-01/87, COPPE/UFRJ-EE (1987). A globally asymptotically stable VS-MRAC was proposed in part I for plants with relative degree one. A VS-MRAC for plants of arbitrary relative degree is presented here. The controller requires only input/output measurements and is free of differentiators.
