摘要:The performance of estimation algorithms depends on the available sensors and their precisions. While higher precisions of sensors provide better estimation accuracy, it may lead to unnecessarily expensive designs and higher operational costs due to the higher costs of high-precision sensing modalities. Also, higher precision can cause interference for other sensors in the environment, such as RADARs, resulting in degradation in the overall system's performance. This article presents a framewo...

摘要:Transition analysis is essential for analyzing and regulating logical control networks (LCNs). The algebraic state-space representation method, which relies on the semitensor product of matrices, has been shown to allow deterministic LCNs to be represented as linear-like systems. However, due to the inherent uncertainty, it is hard to obtain the algebraic expression of an stochastic LCN. A unified paradigm for the transition analysis of LCNs with stochastic and deterministic dynamics is provid...

摘要:Dynamical flow networks serve as macroscopic models for, e.g., transportation networks, queuing networks, and distribution networks. While the flow dynamics in such networks follow the conservation of mass on the links, the outflow from each link is often nonlinear due to, e.g., flow capacity constraints and simultaneous service rate constraints. Such nonlinear constraints imply a limit on the magnitude of exogenous inflow that is able to be accommodated by the network before it becomes overlo...

摘要:This article presents a new numerical method, which approximates Neumann type null controls for the heat equation and is based on the Fokas method. This is a direct method for solving problems originating from the control theory, which allows the realization of an efficient numerical algorithm that requires small computational effort for determining the null control with exponentially small error. Furthermore, the unified character of the Fokas method makes the extension of the numerical algor...

摘要:This article addresses the design of robust linear quadratic regulators for systems affected polynomially by uncertainty constrained in a semialgebraic set. The problem consists of determining a feedback controller that ensures a desired upper bound on the worst-case value of a quadratic cost. Two linear matrix inequality approaches are proposed, the first one based on the construction of a Lyapunov function that weakly depends on the uncertainty, and the second one based on the construction o...

摘要:This article develops a control scheme, based on the use of long short-term memory neural network models and nonlinear model predictive control, which guarantees recursive feasibility with slow time variant set-points and disturbances, input and output constraints and unmeasurable state. Moreover, if the set-point and the disturbance are asymptotically constant, offset-free tracking is guaranteed. Offset-free tracking is obtained by augmenting the model with a disturbance, to be estimated toge...

摘要:It is well known that Lie algebra methods are the leading methods for studying controllability of continuous-time nonlinear systems including bilinear systems, where the controllability problems are usually transformed into the transitivity problems of the corresponding Lie algebras. Unfortunately, it is in general a difficult task to check transitivity of Lie algebras, especially in the high-dimensional cases. In this article, we propose a new notion, named near-transitivity. We focus on unco...

摘要:This article considers the global leader-following event-triggered consensus problem for the input-constrained double-integrator multiagent systems. By utilizing a Lyapunov-like function consisting of a positive semidefinite term and an integral term, a novel bounded static linear event-triggered protocol is proposed to ensure that the global leader-following consensus problem is solved in a fully distributed manner for all undirected communication graphs. In order to avoid continuously monito...

摘要:The input-to-state stability of the nonhorizontal cascade channels with different arbitrary cross section, slope, and friction modeled by Saint-Venant equations is addressed in this article. The control input and measured output are both on the collocated boundary. The proportional-integral (PI) control is proposed to study both the exponential stability and the output regulation of closed-loop systems with the aid of the Lyapunov approach. An explicit quadratic Lyapunov function as a weighted...

摘要:In this work, we propose a new passivity-based sliding mode control (PBSMC) method for mechanical port-Hamiltonian systems. PBSMC is unification of sliding mode control and passivity-based control. It achieves sliding mode control and Lyapunov stability simultaneously by employing an energy-based Lyapunov function. The proposed method gives a family of stabilizing controllers that smoothly interpolates passivity-based control and sliding mode control with design parameters. The freedom is usef...
