摘要：This article studies the risk-constrained linear-quadratic regulation (Rc-LQR) for a class of interconnected systems (ISs) with non-Gaussian noise. The IS is of a weakly connected topology. The standard linear-quadratic regulation (LQR) controller is optimal in expectation for the quadratic cost and, thus, is called risk-neutral LQR (Rn-LQR) controller. However, the Rn-LQR system may suffer from low-probability yet statistically significant/risky events. The Rc-LQR controller can well trade be...

摘要：The purpose of this article is to study the dynamics of a quantum coherent feedback network, where an $N$-level atom is coupled with a cavity and the cavity is also coupled with a single or multiple parallel waveguides. When the atom is initialized at the highest energy level, it can emit multiple photons into the cavity, and the photons can be further transmitted to the waveguides and reinteract with the cavity quantum electrodynamics (cavity-QED) system. The transmission of photons in the wa...

摘要：A new nonlinear integral sliding mode control (ISMC) algorithm for singularly perturbed multiple-inputs and multiple-outputs (MIMO) systems subject to matched and unmatched uncertainties is proposed. The circumstance of fast sensor dynamics in series with the plant exemplifies the results. Using prior knowledge about the sensor dynamics, the ISMC structure and its parameters can be tuned to ensure that the closed loop converges to a suitably small neighborhood of the desired equilibrium. It is...

摘要：Safety is a critical property for control systems in medicine, transportation, manufacturing, and other applications, and can be defined as ensuring positive invariance of a predefined safe set. This article investigates the problems of verifying positive invariance of a semialgebraic set as well as synthesizing sets that can be made positive invariant through control barrier function (CBF)-based control. The key to our approach consists of mapping conditions for positive invariance to sum-of-...

摘要：The order of an aggregated Markov model (AMM) is an index of complexity and is closely related to the reachable subspace of a model. The AMM is called reachable-space reducible when the reachable subspace is not the whole space. Previous results demonstrate that there exists a reduced-order quasi-realization, which may not satisfy the nonnegative constraints, equivalent to a given reachable-space reducible AMM. This article focuses on the structured AMM where the transition and observation mat...

摘要：State estimation of robotic systems is essential to implementing feedback controllers, which usually provide better robustness to modeling uncertainties than open-loop controllers. However, state estimation of soft robots is very challenging because soft robots have theoretically infinite degrees of freedom while existing sensors only provide a limited number of discrete measurements. This work focuses on soft robotic manipulators, also known as continuum robots. We design an observer algorith...

摘要：We present an adaptive form of the simultaneous long-short (SLS) trading strategy, which employs feedback control principles for stock trading. Prior work established the robust positive expectation (RPE) theorem for the SLS strategy, asserting positive expectations of trading profits for stock prices following geometric Brownian motions with unknown parameters. We extend the RPE property to adaptive SLS strategies, which guarantee strictly positive expected profits even in round-trip price sc...

摘要：In this article, we study a pursuit-evasion game between two players with heterogeneous kinematics, where the pursuer is with damped double-integrator dynamics and the evader is with single-integrator dynamics. The pursuer aims at capturing the evader as soon as possible, while the evader wants to avoid or delay the capture. Traditional methods to solve pursuit-evasion games rely on the Hamilton-Jacobi-Isaacs (HJI) equations and retrogressive path equations, which are very complicated and noni...

摘要：In the Ramadge-Wonham supervisory control theory, the only interaction mechanism between supervisor and plant is that the supervisor may enable/disable events from the plant and the plant makes a final decision about which of the enabled events is actually taking place. In this article, the interaction between supervisor and plant is enriched by allowing the supervisor to force specific events (called forcible events) that are allowed to preempt uncontrollable events. A notion of forcible cont...

摘要：This article analyzes aspects of the problem of remote state estimation (RSE) via noisy communication channels for their Blum-Shub-Smale (BSS) computability, motivated by an exemplary application to a formal model of virtual twinning subject to stringent integrity requirements. Computability theory provides a unique framework for the formal and mathematically rigorous analysis of algorithms and computing machines. Therefore, computability theory is essential in the domain of safety- and life-c...
