Partial State Feedback MRAC-Based Reconfigurable Fault-Tolerant Control of Drag-Free Satellite With Bounded Estimation Error

IEEE Transactions on Aerospace and Electronic Systems, 2023
Aiming at the ultraprecision and ultrastable requirements of drag-free control in space detection missions, a multivariable model reference adaptive control (MRAC) scheme is proposed in this article based on partial observation state, to provide adaptive

A novel robust maximum power extraction framework for sustainable PV system using incremental conductance based MRAC technique

Environmental Progress & Sustainable Energy, 2023
This study proposes a maximum power point tracking (MPPT) approach with two components: an Incremental Conductance (INC) MPPT for reference voltage regulation and a Model Reference Adaptive Controller (MRAC) for adjusting the duty cycle of the DC‐DC ...

PF-MRAC-Based Elimination of Sensors in Solar-Powered PMSM Drive-Based Water Pumping System

IEEE transactions on industrial electronics (1982. Print), 2023
The water pumping system powered by solar photovoltaic (PV) array and driven by permanent magnet synchronous motor demands a current-sensor to operate PV array at its maximum power and an encoder to implement field-oriented control of motor. Reduction in

Design of MRAC and Modified MRAC for the Turntable

2020 39th Chinese Control Conference (CCC), 2020
This paper analyzes and compares the model reference adaptive control (MRAC) and modified MRAC for turntables. The conventional MRAC is aimed at the first-order system for two-variable parameter adjustment. Most of plants are second-order systems, including turntables.

MRAC With Adaptive Uncertainty Bounds via Operator-Valued Reproducing Kernels

IEEE Control Systems Letters, 2023
This letter presents three novel model reference adaptive control (MRAC) systems for nonlinear plants in which the matched, nonparametric uncertainty is only known to reside in a vector-valued reproducing kernel Hilbert space (RKHS).

STATE SPACE STRUCTURES IN MRAC

IFAC Proceedings Volumes, 1992
Abstract 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.

MRAC and modified MRAC controller design for level process control

2018 Indian Control Conference (ICC), 2018
This 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.

Yaw-rate-tracking-based Automated Vehicle Path Following: An MRAC Methodology with A Closed-Loop Reference Model

ASME Letters in Dynamic Systems and Control, 2021
Concerning automated vehicles, various path-following controllers have been designed by the model reference adaptive control (MRAC) approach. Through appropriate Lyapunov redesigns, asymptotical stability and signal boundedness are ensured for the path-
