MRAC with reduced state information

IFAC Proceedings Volumes, 2004
Abstract Direct adaptive control algorithms using state variables in control structure are known for their good adaptation capability and tracking performances that result from the fact that they use plant state variables in control law as well as in adaptation law.

PID and MRAC control of a Quadrotor

2019 3rd International Conference on Recent Developments in Control, Automation & Power Engineering (RDCAPE), 2019
A Quadrotor is an Unmanned Aerial Vehicle (UAV) which has four rotors. It is a non-linear multivariable system which is highly underactuated. Voltage-based approach using Newton-Euler technique is used to derive the quadrotor's equations-of-motion. These equations are then used to develop a Simulink model and the output responses for roll, pitch and ...

A Novel MRAC of Induction Motor

IEEE 36th Conference on Power Electronics Specialists, 2005., 2006
MRAC (model reference adaptive control ) is one effective scheme for parameter identification in a flux field-oriented control system of induction motors. But most of the existent available reference models used in this field are based on the static models of induction motors, and so the transient performances are always unsatisfactory.

A Design of Nonlinear MRACS and the Proof of Stability

IFAC Proceedings Volumes, 1990
Abstract This paper shows a design of nonlinear MRACS and the proof of gloval stability. Nonlinear systems which are dealed in this paper have the property of norm constraints. We design nonlinear MRACS by combineing nonlinear model following control systems and papameter adjustable laws of Kleisselmeier type.

Output Feedback M-MRAC

AIAA Guidance, Navigation, and Control (GNC) Conference, 2013
This paper presents design and performance analysis of a modified reference model MRAC (M-MRAC) architecture in the output feedback framework for a class of singleinput single-output (SISO) uncertain systems. It is shown that the modification of the reference model by the tracking error feedback enables the designer to achieve a desired level of ...

MRAC for A Launch Vehicle Actuation System

2015
Actuators are used to provide Thrust Vector Control (TVC) for lifting the launch vehicle and its payload to reach its space orbits. The TVC comprises actuation and power components for controlling the engines direction and thrust to steer the vehicle. Here the actuator considered is a linear Electromechanical Actuator (EMA) system.

Augmented-MRAC for quadrotor UAVs with parameter change

2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2016
Multirotor unmanned aerial vehicles (MAVs) with the capability of interaction with their surroundings have recently received increasing attention. However, the rapid change parameters during flight present a challenge for the stable control of MAVs. In this paper, the baseline controller of a quadrotor is developed based on classical model reference ...

MRAC ALGORITHM FOR HIGH RELATIVE DEGREE PLANTS

IFAC Proceedings Volumes, 1995
Abstract The principal aim of this paper is to present a new algorithm for the control of continuous time linear systems with a large relative degree and unknown parameters. If the standard approach is used for these systems, the controller structure is very complicated and implementation is problematic.

Model Updating Improves Performance of an MRAC Design

IFAC Proceedings Volumes, 1983
Abstract We will discuss the technique of model updating to improve the performance of a MRAC design with state feedback. At specified time intervals the state of the reference model is adjusted to actual state of the system, which can improve the convergence of the parameters, reduces control effort and yields faster response times.
