Abstract

In this paper, we consider performance output tracking for a wave equation with a general boundary disturbance. The control and the disturbance are unmatched. Different from the existing results, the hidden regularity, instead of the high gain or variable structure, is utilized in the adaptive servomechanism design. As a result, we are able to cope with more complicated and general disturbances. Moreover, the performance output can track the reference signal exponentially, and at the same time, all the states of the subsystems involved are uniformly bounded. More specially, the overall closed-loop system is exponentially stable when the disturbance and reference are disconnected to the system. The numerical simulations are presented to illustrate the effect of the proposed scheme. (C) 2016 Elsevier B.V. All rights reserved.

Output tracking for a 1-D wave equation with velocity recirculation via boundary control

Shuangxi Huang, Feng-Fei Jin

Summary: This paper discusses the problems of output tracking and disturbance rejection for a 1-D wave equation with in-domain feedback/recirculation of an intermediate point velocity. A disturbance estimator is designed using the active disturbance rejection control method to estimate the disturbance, and an observer is proposed and shown to exponentially converge to the original system. An output feedback controller is constructed based on the designed observer. The resulting closed-loop system is well-posed, with all internal signals bounded, and the output exponentially tracks the reference signal. Theoretical results are validated through numerical simulations.

Performance output tracking for a one-dimensional heat equation with input delay

Li Wang

Summary: This paper focuses on performance output tracking for a one-dimensional heat partial differential equation with unknown external disturbance and non-collocated configuration. The control input in this system is subject to a time delay. By representing the time delay as a first-order hyperbolic equation, the control system is modeled as a cascade construction, where the transport equation can be seen as the actuator dynamics of the heat partial differential system. The difficulties caused by the input delay are addressed by compensating for the actuator dynamics. A full state feedback law is constructed to achieve performance output tracking, and an error-based observer is successfully designed. The exponential stability of the closed-loop system and the well-posedness of the observer are proven.

Output tracking for an Euler-Bernoulli beam equation with moment boundary control and shear boundary disturbance

Zhan-Dong Mei, Yi-Lin Mo

Summary: This paper focuses on performance output tracking for an Euler-Bernoulli beam equation with moment boundary control and shear boundary disturbance. The authors propose an infinite-dimensional disturbance estimator and an output feedback control law to compensate for the disturbance. It is proved that the performance output exponentially tracks the reference signal, and the closed-loop system remains bounded. The importance of this work lies in addressing the shear boundary term and presenting key steps to handle the problem.

Output tracking anti-disturbance control for turbofan systems

Yuxuan Gao, Ying Zhao, Yu Liu, Zhuo-Rui Pan, Rui Wang

Summary: A new output tracking control strategy is proposed for turbofan systems affected by multiple disturbances. The aim is to improve the output tracking performance while mitigating the effect of the disturbances. An observer is used to estimate the unmeasurable modeled disturbance and a corresponding controller is designed to optimize the output tracking performance and disturbance restraint. The developed control scheme is implemented on a hardware-in-loop simulation platform to enhance the output tracking performance of the turbofan system.

Summary: This paper discusses the problem of exponential tracking and disturbance rejection for the nonlinear unstable gradient-dependent wave equation using boundary control. By splitting the tracking problem into a linear exponentially stable wave equation and a nonlinear dynamical regulator wave equation, an explicit boundary controller is constructed. The theoretical results are confirmed through a numerical example.

STRICHARTZ ESTIMATES AND LOCAL REGULARITY FOR THE ELASTIC WAVE EQUATION WITH SINGULAR POTENTIALS

Seongyeon Kim, Yehyun Kwon, Ihyeok Seo

Summary: In this work, we obtain weighted L-2 estimates for the elastic wave equation perturbed by singular potentials, including the inverse-square potential. Additionally, we deduce Strichartz estimates under the sole ellipticity condition for the Lame operator -Delta*, improving upon previous results which required a stronger condition for ensuring self-adjointness of -Delta*. Furthermore, by establishing local energy estimates for the elastic wave equation, we also demonstrate that the solution possesses local regularity.

Output tracking and disturbance rejection control for switched systems under asynchronous switching

M. Vijayakumar, R. Sakthivel, F. Kong, S. Marshal Anthoni

Summary: In this article, the output tracking and disturbance rejection problem for a class of switched systems with state time-varying delay under asynchronous switching are discussed. Proportional-integral control law is implemented to achieve the required tracking performance, and an improved equivalent-input-disturbance estimator is used to estimate and suppress external disturbances. An average dwell time approach is employed to establish a set of conditions for the structure of linear matrix inequalities through setting a proper choice of multiple piecewise Lyapunov-Krasovskii functional. Two numerical examples and simulations of a DC motor driving model are presented to validate the efficiency and applicability of the proposed control synthesis.

Inverse optimal control for averaged cost per stage linear quadratic regulators

Han Zhang, Axel Ringh

Summary: Inverse Optimal Control (IOC) is a powerful framework for learning behavior from expert observations. In this study, we focused on identifying the cost and feedback law from observed trajectories. We proved that identifying the cost is generally an ill-posed problem, but we constructed an estimator for the cost function and showed that it provides a statistically consistent estimate for the true underlying control gain. The constructed estimator is based on convex optimization and exhibits statistical consistency in practice.
