In this paper, a control architecture merging a reference Governor and a model reference adaptive control law is tested on a high-fidelity Simulink model of a Parrot Bebop 2 Drone. This system is considered to be subject to velocity constraints, and the flight simulations are performed in the presence of simulated matched uncertainties to recreate the typical uncertain environment in which a drone operates. The proposed control framework allows for precise tracking and constraints enforcement despite the uncertainties and the perturbations acting on the system. The novelty of the approach consists of exploiting the adaptive law performance to build a robust reference Governor with limited conservatism. As a result, larger uncertainties can be handled, and the computational complexity of the governor's optimization problem is limited compared to the standard robust reference Governor strategy.

This paper develops a new model reference adaptive control for multi-variable systems with input disturbance. The controller structure is established by using reduced-order state observer and the direct estimate of nominal controller parameters. The output matching condition, new tracking error, estimate error as well as adaptive properties are developed depending on the available signals, rather than the state or output signals in the existing schemes. The new output matching condition is crucial to the analysis of model reference adaptive control output tracking. With this presented control design, the desired system properties are achieved including system stability and output tracking, and the simulation results indicate the disturbance rejection ability of the developed scheme.

Output regulation theory is a highly effective method for achieving accurate time-varying command following, but redesigning its control architecture for different time-varying command profiles can be necessary. Yet, this often results in control architectures with gain matrices of significantly increased dimensions. This paper focuses on model reference adaptive control of uncertain dynamical systems. Specifically, our contribution is a gradient descent-based term that alters both reference model trajectories and the control signal to enable time-varying command following. In contrast to output regulation theory, the proposed term can follow every potential time-varying command profile without specificity as the gain of this term increases. In addition to the presented theoretical results, illustrative numerical examples are included to show the efficacy of the proposed gradient descent-based term for time-varying command following. © 2024 IEEE.

In this contribution we extend the classical update law of the certainty equivalence based (indirect) model reference adaptive control (MRAC) with an additional feedthrough error term. We use a linear state-space representation of the parameter estimation error in order to construct a Lyapunov function. Without unstructured uncertainties, we can show asymptotic stability of the closed loop. Even for relatively high adaptation gains the algorithm can reduce the oscillations of the state variables. In case of unstructured input uncertainties, the additional term reduces the model following error drastically without increasing the control signal for low frequency unstructured uncertainties. For the simplified pure linear case we analyze the effect of the additional proportional error feedthrough in the adaptation law showing its similarity to a disturbance observer. As a simulation example the wing-rock dynamics are reconsidered.

This abstract introduces a cuttingedge approach to power management in space systems through the development of a model reference adaptive control (MRAC) buck converter. This converter is designed to dynamically optimize its output in response to variable loads while concurrently addressing the challenges posed by Single Event Upsets (SEUs) in electronic systems. The proposed converter, constructed primarily with Commercial Off-The-Shelf (COTS) components, seeks to alleviate the escalating costs associated with space-grade components. The utilization of MRAC facilitates real-time adaptation of control parameters, enhancing the converter's efficiency under dynamic load conditions. This adaptability is crucial in space environments where fluctuating power demands are prevalent. Additionally, the converter incorporates a robust SEU detection mechanism, triggering an intelligent power cycling response upon detection. This feature ensures the system's resilience to radiation-induced upsets, further bolstering the reliability of the spaceborne electronics. This abstract delineates the theoretical foundation, design intricacies, and anticipated advantages of the adaptive MRAC-based buck converter. By embracing COTS components, the design not only addresses economic concerns but also aligns with a sustainable and accessible paradigm for space system development. The potential ramifications of this innovation span diverse space applications, contributing significantly to the progress and dependability of electronic systems in the challenging space exploration environment. © 2024 International Astronautical Federation, IAF.

In this paper, we explore the capabilities of model reference adaptive controllers for better response to uncertain over-actuated nonlinear dynamical systems that use nonlinear refer ence models. It is common practice to use linear reference models in controllers;however, this can lead to limitations on the closed-loop system performance;thus, there exists a need to operate a nonlinear reference model. To overcome this limitation and leverage the full capabilities of high-performance uncertain dynamical systems, a controller is proposed that uses a nonlinear reference model. We provide the stability analysis that indicates system error between the uncertain dynamical system and the nonlinear reference model vanishing asymptotically in the steady state. A numerical example of hexacopter rotational dynamics is included to show the efficacy of the proposed controller. © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA.

The paper discusses the concentration control in Continuous Stirred Tank Reactors (CSTR) using another CSTR as a reference model. The PI controller regulates the reference model, which adjusts the model reference adaptive controller (MRAC). The neural controller is then tuned with the model identified from the second CSTR. The controllers' performance is assessed through the utilization of MATLAB/SIMULINK aiming to illustrate and enhance the system's concentration and stability. The simulation results are compared with the model reference adaptive controller MIT and Lyapunov rules. © 2024 IEEE.

The study considers model reference adaptive control for a single-input, single-output discrete-time system using an idea of the virtual reference feedback tuning (VRFT). The standard VRFT resolves a model reference control problem using one-shot experimental input-output data instead of a mathematical controlled plant model. The study provides an online tuning method for controller parameter to follow a prescribed reference model output for the closed-loop output. The main feature in the study is to achieve asymptotically tracking to step-type reference signals under unmatched controller structures. The effectiveness of the proposed method is shown through a numerical example. © 2024 IEEE.

Due to their large volume structure, when a heavy vehicle encounters sudden road conditions, emergency turns, or lane changes, it is very easy for vehicle rollover accidents to occur;however, well-designed suspension systems can greatly reduce vehicle rollover occurrence. In this article, a novel semi-active suspension adaptive control based on AdaBoost algorithm is proposed to effectively improve the vehicle rollover stability under dangerous working conditions. This research first established a vehicle rollover warning model based on the AdaBoost algorithm. Meanwhile, the approximate skyhook damping suspension model is established as the reference model of the semi-active suspension. Furthermore, the model reference adaptive control (MRAC) system is established based on Lyapunov stability theory, and the adaptive controller is designed. Finally, on the same road condition, the rollover warning control simulations are carried out under the following conditions: the 180-degree step, the fishhook, and the double-lane-change condition. Simulation results show that the proposed reference adaptive control based on the AdaBoost algorithm for rollover control can effectively predict vehicle rollover in early warning and improve the anti-rollover capability of vehicles.
