STATE SPACE STRUCTURES IN MRAC
IFAC Proceedings Volumes, 1992Abstract MRAC structures for the plants with accessible state variables are considered. A direct adaptation law for nonlinear systems is formulated. It is shown that it covers the well-known adaptation laws for linear systems as a special case. Both centralized and decentralized control structures are considered.

2018 15th International Conference on Control, Automation, Robotics and Vision (ICARCV), 2018
In this paper, we apply the method of control theory to machine learning, proposing a new multiplication update algorithm combined with adaptive control theory, we name it MRAC-MU algorithm. A new parameter updating law is obtained according to Lyapunov stability theorem.

MRAC and Modified MRAC Controller Design for Level Process Control
2018 Indian Control Conference (ICC), 2018This paper gives the comparative analysis of conventional Model Reference Adaptive Controller (MRAC) and Modified MRAC. The Modified MRAC is designed by a combination of MRAC and PID controller. It gives improved dynamic performance of the process. The performance of the modified MRAC is compared with conventional MRAC and it found more effective.

MRAC Implementation for Electric Throttle Valve
2020 10th International Conference on Advanced Computer Information Technologies (ACIT), 2020Design, implementation and testing of a model reference adaptive controller for an electric throttle valve are presented. An important step by design an adaptive controller is to find an adaptation mechanism. For this purpose, we employed the Lyapunov stability theory.

Convergence performance comparisons of PID, MRAC, and PID + MRAC hybrid controller
Frontiers of Mechanical Engineering, 2016This study proposes a hybrid controller by combining a proportional-integral-derivative (PID) control and a model reference adaptive control (MRAC), which named as PID + MRAC controller. The convergence performances of the PID control, MRAC, and hybrid PID + MRAC are also compared. Through the simulation in Matlab, the results show that the convergence

Robust MRAC-Based Fault Tolerant Control for Additive and Multiplicative Faults in Nonlinear Systems
IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2012 In this paper, three different types of faults (abrupt-additive, gradual-additive and multiplicative) are introduced to two new reconfigurable structures for Fault Tolerant Control (FTC) of a Single Input- Single Output (SISO) non-linear process.

Data driven MRAC with parameter convergence
2015 IEEE Conference on Control Applications (CCA), 2015The convergence of parameters in model reference adaptive control (MRAC) requires that a restrictive persistence of excitation (PE) condition be satisfied. A recent data driven approach, concurrent learning, uses past input-output data in conjunction with standard adaptive laws to ensure parameter convergence without needing the PE condition.
