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...

摘要：This article is concerned with the trajectory tracking control problem for the wheeled mobile robots (WMRs) subject to actuator faults. The challenge lies in the partial loss of effectiveness of the actuated wheels which results in the loss of strong controllability of the WMR, rendering the classical fault-tolerant control methods infeasible. To overcome this obstacle, a novel mixed-gain adaption technique is put forward and is skillfully combined with the robust prescribed performance contro...

摘要：Whether a population of decision-makers reach a state of satisfactory decisions is a fundamental problem in studying collective behaviors. In the framework of evolutionary game theory, researchers used potential functions to establish equilibration under best-response and imitation update rules by imposing conditions on the individuals' utility functions, and in turn to control the population toward a desired equilibrium. Nevertheless, finding a potential function is often daunting, if not nea...

摘要：In this article, we study the problem of privacy-preserving average consensus from a different perspective. Previous research has mainly focused on designing privacy augmentation mechanisms for classical average consensus algorithms, which can lead to overhead (in the form of parameters exchanged between agents or extra privacy operations). Motivated by the framework of expressed and private opinions within social networks, we propose an alternative iterative algorithm to simultaneously update...

摘要：Consider a linear system subject to stochastic disturbances and a path to be followed by a system's output. The path-following problem is posed here as choosing both the control input and the speed along the path to minimize the expected value of a quadratic function of the control input and of the error between the output and the resulting trajectory. The optimal control input policy for the deterministic version (no stochastic disturbances) is first provided and shown to be the sum of linear...

摘要：We study tracking control for uncertain nonlinear multi-input, multi-output systems modeled by rth order functional differential equations (encompassing systems with arbitrary strict relative degree) in the presence of input constraints. The objective is to guarantee the evolution of the tracking error within a performance funnel with prescribed asymptotic shape (thus achieving desired transient and asymptotic accuracy objectives), for any sufficiently smooth reference signal. We design a nove...

摘要：Despite the recent development of distributed constrained optimization algorithms in the literature, it is still a challenging issue to construct distributed algorithms to efficiently solve the constrained optimization problem with convergence rate guarantees, especially for the case with general constraints and unbalanced time-varying digraphs. This article aims to investigate the distributed discrete-time optimization problem over time-varying unbalanced digraphs with general constraints inc...

摘要：Strategic decision-making in uncertain and adversarial environments is crucial for the security of modern systems and infrastructures. A salient feature of many optimal decision-making policies is a level of unpredictability, or randomness, which helps to keep an adversary uncertain about the system's defensive strategies. This article seeks to explore decision-making policies on the other end of the spectrum-namely, whether there are benefits in revealing one's strategic intentions to an oppo...

摘要：The distributed computation of a Nash equilibrium in aggregative games is gaining increased attention in recent years. Of particular interest is the coordinator-free scenario where individual players only observe the decisions of their neighbors due to practical constraints. Given the noncooperative relationship among participating players, protecting the privacy of individual players becomes imperative when sensitive information is involved. We propose a fully distributed equilibrium-seeking ...
