Accurate Sub-Millimeter Servo-Pneumatic Tracking using Model Reference Adaptive Control (MRAC)
International Journal of Fluid Power, 2010A model reference adaptive controller (MRAC) for compensating friction and payload uncertainties in a servopneumatic actuation system is presented in this paper. A friction model combining viscous and Coulomb friction is formulated within the framework of an adaptive controller.

Analysis of memristor based model reference adaptive controller (MRACs)
2014 International Conference on Control, Instrumentation, Communication and Computational Technologies (ICCICCT), 2014In this paper, for the first time, we propose an adaptive controller based on a new electrical element “Memristor” which will not only improve the system stability and performance, but also maintain that stability for a longer time, irrespective of different perturbation factors.

SPIE Proceedings, 2004
This paper investigates the feasibility of direct model reference adaptive control (MRAC) scheme for the vibration suppression of a smart flexible beam. Direct model reference adaptive controller whose parameters are updated directly from the Lyapunov-based adaptive laws is developed. The adaptive laws for updating the controller parameters are derived

BPD computation and model reference adaptive control (MRAC) of Hammerstein plants
IEE Proceedings - Control Theory and Applications, 1995Summary: A large class of control strategies relies on computation of the output gradient vector. Recently the concept of block partial derivatives (BPD) and the associated algebra have been introduced to facilitate the computation of the gradient vector in nonlinear systems. We propose a simpler procedure for BPD computation.

Volume 1: Active Materials, Mechanics and Behavior; Modeling, Simulation and Control, 2009
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 ...

This paper presents an angular shaft speed control scheme of an induction motor. The induction motor modelling is performed through vector control with rotor flux orientation. The used control strategy is variable structure model reference adaptive control, that is applied to control uncertain plants.

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.

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 ...
