Identification of FIR Systems With Binary Input and Output Observations IEEE Trans. Autom. Control (IF 5.625) Pub Date : 2020-12-03 Alex S. Leong; Erik Weyer; Girish N. Nair
This article considers the identification of finite-impulse response systems, where information about the inputs and outputs of the system undergoes quantization into binary values before transmission to the estimator. In the case where the thresholds of the input and output quantizers can be adapted, we propose identification schemes that are strongly consistent for Gaussian distributed inputs and

The article is concerned with active disturbance rejection control of a heat equation. The considered heat equation satisfies the Dirichlet boundary condition on one part of the boundary. On the other part of the boundary is located a Neumann boundary control. The heat equation system suffers from both a model uncertainty in the heat flow modeling and an unknown external disturbance. Our control approach

Combining Pontryagin's Principle and Dynamic Programming for Linear and Nonlinear Systems IEEE Trans. Autom. Control (IF 5.625) Pub Date : 2020-09-03 Mario Sassano; Alessandro Astolfi
To study optimal control and disturbance attenuation problems, two prominent—and somewhat alternative—strategies have emerged in the last century: dynamic programming (DP) and Pontryagin's minimum principle (PMP). The former characterizes the solution by shaping the dynamics in a closed loop ( a priori unknown) via the selection of a feedback input, at the price, however, of the solution to (typically

Hankel Singular Values and LQG Characteristic Values of Discrete-Time Linear Systems in Cascade With Inner Systems IEEE Trans. Autom. Control (IF 5.625) Pub Date : 2020-07-24 Maide Bucolo; Arturo Buscarino; Luigi Fortuna; Mattia Frasca; Giuseppe Nunnari
Recent results have shown that, for continuous-time systems obtained by cascading an asymptotically stable system with an inner system, the first $n$ Hankel singular values are greater than or equal to those of the original system. Similarly, cascading a system in minimal form with an inner system, the same property holds for the linear quadratic Gaussian (LQG) characteristic values. In this article

Robust Motion Planning for Uncertain Systems With Disturbances Using the Invariant-Set Motion Planner IEEE Trans. Autom. Control (IF 5.625) Pub Date : 2020-07-09 Claus Danielson; Karl Berntorp; Avishai Weiss; Stefano Di Cairano
The invariant-set motion planner uses a collection of safe sets to find a collision-free path through an obstacle-filled environment [1] – [4] . This article extends the invariant-set motion planner to systems with persistently varying disturbances and parametric model uncertainty. This is accomplished by replacing the previously used positive invariant sets with robust positive invariant sets. Since

Continuous-Time Model Identification From Filtered Sampled Data: Error Analysis IEEE Trans. Autom. Control (IF 5.625) Pub Date : 2020-07-01 Xiao-Li Hu; James S. Welsh
In this article, an upper bound is established for the estimation error of a standard least squares (LS) algorithm used to identify a continuous-time model from filtered, sampled input–output data. It is found that the error has three constituent components due to the initial conditions, observation noise, and sample period. In particular, the initial condition bias is bounded by $O(1/[N\Delta t])$

This article deals with output feedback selection in linear time-invariant structured systems. We assume that the inputs and the outputs are dedicated , i.e., each input directly actuates a single state and each output directly senses a single state. Given a structured system with dedicated inputs and outputs and a cost matrix that denotes the cost of each feedback connection, our aim is to select

We study the reduction of degrees of freedom for the equations that determine necessary optimality conditions for extrema in an optimal control problem for a multiagent system by exploiting the physical symmetries of agents, where the kinematics of each agent is given by a left-invariant control system. Reduced optimality conditions are obtained using techniques from variational calculus and Lagrangian

This article studies the remote state estimation problem of linear time-invariant systems with stochastic event-triggered sensor schedules in the presence of packet drops between the sensor and the estimator.

A Novel Method for Stability Analysis of Time-Varying Delay Systems IEEE Trans. Autom. Control (IF 5.625) Pub Date : 2020-06-10 Yongqing Wang; Haibo Liu; Xu Li
The Lyapunov–Krasovskii functional (LKF) method is an effective tool to obtain delay-dependent stability criteria of time-varying delay systems. However, in the method, the requirement that there must exist an appropriate LKF for a system with a delay varying in a delay interval is too strict and may lead to considerable conservativeness. In order to get less conservative stability criteria, a novel

We propose a new robust recursive fixed-interval smoother for nonlinear systems under non-Gaussian process and measurement noises, i.e., the nominal Gaussian noise is polluted by large noise from unknown distributions. Taking advantage of correntropy in handling non-Gaussian noise, a robust Rauch–Tung–Striebel smoother is derived according to the maximum-correntropy-criterion-based cost functions with

We consider time synchronization attack against multisystem scheduling in a remote state estimation scenario where a number of sensors monitor different linear dynamical processes and schedule their transmissions through a shared collision channel. We show that by randomly injecting relative time offsets on the sensors, the malicious attacker is able to make the expected estimation error covariance

This article studies novel attack and defense strategies, based on a class of stealthy attacks, namely the zero-dynamics attack (ZDA), for multiagent control systems. ZDA poses a formidable security challenge since its attack signal is hidden in the null space of the state-space representation of the control system and hence it can evade conventional detection methods. An intuitive defense strategy

Sampling Strategies for Data-Driven Inference of Input–Output System Properties IEEE Trans. Autom. Control (IF 5.625) Pub Date : 2020-05-15 Anne Koch; Jan Maximilian Montenbruck; Frank Allgöwer
Due to their relevance in controller design, we consider the problem of determining the $\mathcal {L}^2$ -gain, passivity properties, and conic relations of an input–output system. While, in practice, the input–output relation is often undisclosed, input–output data tuples can be sampled by performing (numerical) experiments. Hence, we present sampling strategies for discrete time and continuous time

As a quantitative criterion for privacy of “mechanisms” in the form of data-generating processes, the concept of differential privacy was first proposed in computer science and has later been applied to linear dynamical systems. However, differential privacy has not been studied in depth together with other properties of dynamical systems, and it has not been fully utilized for controller design. In

In the standard linear, time-invariant feedback system, controllers that achieve diagonal decoupling and closed-loop stability exist if and only if the plant satisfies the diagonal denominator condition or has no coinciding poles and zeros in the region of instability. A simple and systematic decoupling design procedure is presented under each of these conditions. The closed-loop poles can be placed
