摘要：The aim of this article is to design static output feedback controllers for multi-input-multi-output (MIMO) linear time-invariant (LTI) systems, with the requirements of positivity and asymptotic stability to be guaranteed in closed-loop systems. By expressing the matrix product $KC$ as a sum of rank one matrices, new necessary and sufficient conditions for the existence of a static output feedback controller are derived in terms of linear programming (LP) conditions. One of the advantages of ...

摘要：This article is devoted to one-class fault detection in linear discrete-time varying (LDTV) systems with uncertainties. Specifically, following the Hilbert Projection theorem, the residual generation problem is solved by means of an orthogonal projection of process data onto system subspaces in Hilbert space. The resulted Pythagorean equation enables establishing an adaptive threshold driven by the residual signal and using gap metric as the similarity measure. In this projection-based fault d...

摘要：In this article, we investigate the joint problem of dynamics learning and tracking control for a class of parabolic partial differential equation (PDE) systems with infinite-dimensional uncertain nonlinear dynamics. A new learning control scheme is proposed based on the deterministic learning (DL) theory. One key feature of the proposed scheme is its capability of accurately learning the system's nonlinear uncertain dynamics during real-time tracking control with provable stability and conver...

摘要：In this article, we consider the centralized optimal estimation problem in spatially distributed systems. We use the setting of spatially invariant systems as an idealization for which concrete and detailed results are given. Such estimators are known to have a degree of spatial localization in the sense that the estimator gains decay in space, with the spatial decay rates serving as a proxy for how far measurements need to be shared in an optimal distributed estimator. In particular, we exami...

摘要：In the domain of multiplayer pursuit-evasion games, it is crucial to address the practical aspects of the players' heterogeneity, the distributed control manner, and the pursuers' goal of minimum makespan. However, the three topics have received limited attention in existing literature, both separately and in combination. In this article, we address the multiplayer pursuit-evasion game integrating these key topics, where the pursuers with simple motions strive to capture as many evaders, chara...

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：This article focuses on online composite optimization over multiagent networks. In the distributed setting, each agent has its own local loss function, which consists of a convex, strongly convex or strongly convex and smooth function, and a time-varying nonsmooth regularizer. Two distributed online algorithms are proposed and corresponding dynamic regrets are analyzed. Two proposed algorithms are based on signs of relative states. The first algorithm obtains O(root T(C-T + 1)) dynamic regret ...

摘要：In the context of increasingly networked control systems, this article concentrates on the noncollocated control issue of input and output quantization for industrial processes governed by semilinear parabolic partial differential equation (PDE) systems. Both the control and measurement signals are quantized and transmitted through the network, which causes signal errors and reduces the stability and robustness of the system. A Luenberger-type PDE observer is developed to overcome the control ...

摘要：Information compression techniques are majorly employed to reduce communication cost over peer-to-peer links. In this article, we investigate distributed Nash equilibrium (NE) seeking problems in a class of noncooperative games over directed graphs with information compression. To improve communication efficiency, a compressed distributed NE seeking (C-DNES) algorithm is proposed to obtain an NE for games, where the differences between decision vectors and their estimates are compressed. The p...
