The security issue in cyber-physical systems has attracted growing interests in the last decades. This paper considers how false data injection attack can degrade the estimation quality of a remote state estimation system. In this system, smart sensors measure a dynamic process and send preprocessed data through a communication network to a remote estimator to estimate the process. It is assumed that there are malicious attackers in the communication network, who are able to obtain and falsify all the data sent by the sensors. It is common that the remote estimator is equipped with a residue-based detector to detect potential attacks. We propose a class of deception attack and analyze its feasibility. We show that the proposed attack enables the attacker to inject false data into the remote estimator without being detected. We derive a criterion to judge the optimality of performance of this type of attack in the sense of maximizing the estimation error covariance. Furthermore, we find that a simple linear attack strategy, which flips the sign of intercepted signal, satisfies the optimality criterion. We present numerical examples to illustrate our theoretical results.

Currently, the multi-legged robots have to confront the problem of low energy utilization that restricts the moving radius of robots. Aimed at the problem of energy consumption for mobile robots, this paper provides the analysis in terms of the gait planning. Firstly, two kinds of gait curves Respectively, cycloid curve and Bezier curve are introduced and the main difference of two gait patterns is that the Bezier curve can achieve the swing leg retraction (SLR). The length of step (S), the height of step (H) and the duty ratio of gait cycle (β) are set as the primary research points about the gait of mobile robot. In this work, we formulate two indexes to quantitatively describe the performance of the quadruped robot and related simulations are carried out for gait parameters. Finally, the results provide some recommendations for the gait planning of the quadruped robot, that is, the changes of gait parameters influence the index of energy consumption and SLR can effectively reduce energy consumption.

For a class of unstable discrete-time multi-variable switched systems with parametric uncertainty, an identification scheme is developed in this paper. Specifically, the identification algorithm is derived to identify the parameter vectors of potential subsystems based on the idea of least geometric mean squares. Furthermore, an neural network classifier is put forward for partition of the identified subsystems. Finally, feasibility and effectiveness of the proposed identification scheme are verified by numerical simulations, which show that the desirable identification performance is guaranteed with the proposed scheme. © 2015

This paper addresses the tuning problem of a proportional-integral-derivative(PID) controller with notch filter for flexible space structure model based on the particle swarm optimization (PSO). For flexible structures, once vibration occurs, PID controller often fails to suppress the high amplitude and high order vibration in the system. Notch filter is used to minimize the effect of bending vibration caused by flexible structure but it may decrease of stability margin. In order to minimize the effect of bending vibration and guarantee both stability margin and time response performance at the same time, PSO algorithm is introduced to optimize both the PID controller and notch filter parameters. Simulation results demonstrate the effectiveness of the proposed design strategy. © 2016, Fuji Technology Press. All rights reserved.

Learning to Win in Evolutionary Two-person Boolean Game with Fixed Strategy Updating Rule

IFAC-PapersOnLine 2015年第28期48卷 520-525页

This paper introduces an algorithm to learn the strategy updating rule for a two- person Boolean game using the records of the history strategies and game results. The two-person game in this paper is introduced as a zero-sum game along with a Boolean strategy set, and the strategies are governed by fixed Boolean functions whose arguments are the history strategies and game results with additive binary noise, which can be modeled as a stochastic Boolean dynamic system. However, for this easy-to-play game, there is no effective convenient methods to win more often. To achieve this goal, a learning algorithm based on Boolean regression and maximum-likelihood estimation is put forward to learn the strategy updating rule and the noise property using the records of the history strategies and game results. In addition, extensive simulations via actual examples have illustrated the effectiveness of the proposed learning algorithm. © 2015
