摘要：In cyber-physical systems (CPS), the networked structure not only enhances the accessibility of data, but also introduces the risk of cyber attacks. The stealthy attacks that are undetected by the monitoring system, are the most dangerous type of cyber attacks. In this article, we introduce a new attack strategy to call attention to the problem of stealthy cyber attacks on CPS. The proposed attack scenario does not require access to all control input signals and sensor output signals, so it ne...

摘要：In this article, we investigate the enforcement of opacity via supervisory control in the context of discrete-event systems. A system is said to be opaque if the intruder, which is modeled as a passive observer, can never infer confidently that the system is at a secret state. The design objective is to synthesize a supervisor such that the closed-loop system is opaque even when the control policy is publicly known. In this article, we propose a new approach for enforcing opacity using nondete...

摘要：This article discusses the remote state estimation over unreliable links, where the packet dropouts occur from the sensor side to the filter, for discrete-time systems with both bounded-power disturbances and white Gaussian noises. A cascaded estimation scheme with enhanced robustness is proposed, driven by the residual signal related to the modeling mismatch. The estimation gains are characterized by two modified algebraic Riccati equations (MAREs), together with a complete and rigorous stabi...

摘要：We consider the observation problem for a particular class of bidimensional systems with scalar output, which requires the consideration of an embedding in a higher dimension for the usual high-gain observer synthesis. We propose a new approach that does not require any coordinates transformation. This approach is based on the design of a set of estimators running in parallel in the same dimension than the original system. Each estimator uses the knowledge of the first two derivatives of the o...

摘要：In this article, a coalitional robust model predictive controller for tracking target sets is presented. The overall system is controlled by a set of local control agents that dynamically merge into cooperative coalitions or clusters so as to attain an efficient tradeoff between cooperation burden and global performance optimality. Within each cluster, the agents coordinate their inputs to maximize their collective performance, while considering the coupling effect with external subsystems as ...

摘要：We propose the ensemble Kalman smoother multiple distribution estimation filter (EnKS-MDEF) for nonlinear state estimation problems. The EnKS-MDEF is an example of the multiple distribution estimation filter (MDEF), which is a particle filter (PF) that estimates the filtered state probability density function (pdf) using multiple conditional state pdfs. The one step behind (OSB) smoothed state pdf used for calculating the filtered state pdf of the MDEF is approximated by the ensemble Kalman sm...

摘要：In this article, we study a supervisory control problem under a constraint on memory size as well as a constraint described by a class of quantitative linear temporal logic, which enables us to consider how well the specification is satisfied. Our control objective is to design a finite-memory supervisor such that the satisfaction value of the specification formula on the controlled system is larger than or equal to a given threshold. We adopt a Safraless synthesis methodology and reduce the p...

摘要：In this article, the compositedisturbance rejection control approach is established for discrete-time Markovian jump systems with unknown external disturbance. With the transformed system in the regular form, a new mode-dependent disturbance observer is proposed to estimate the unknown disturbance in the absence of the exosystem of the disturbance. Then, the chattering-free controller is designed in the backstepping framework, and the disturbance estimate is incorporated to achieve active dist...

摘要：This article is concerned with the output-feedback tracking control problem for a class of nonlinear systems. The challenge lies in how to drive the tracking error to a prescribed region in a given time globally, under both unknown nonlinear functions and unknown virtual control coefficients. To deal with the unknown control direction, an orientation function is exploited in lieu of the Nussbaum gain technique, the supervisory switching strategy, and the parameter estimation approach. To attai...
