In this paper, we propose a stochastic bounded confidence model. At every time slot, each individual receives an external social signal which is the average of opinions of its neighbors. Then agents compare the signals with their own personal biases which are defined as the initial values that ones hold. With positive probability, the agents either accept the opinion or persuade themselves with the help of personal prejudices. The probability of acceptance is reversely proportional to the opinion discrepancy between the signal and the bias. The model is modified as a continuous opinions discrete actions (CODA) model and thus is a Markov chain taking values on a finite state space. It is verified that the chain is aperiodic and finally converges in distribution to some invariant measure. The classification of states shows that the influences of distant opinions will boost consensus while the presence of personal biases promote clustering. The model also combines DeGroot model with Friedkin-Johnson model as well, by using a bounded confidence framework.

This paper studies the robust state agreement of nonlinear multi-agent systems in the presence of measurement disturbances. With the switching topology satisfying a mild joint connectivity condition, it is proved that robust state agreement can be achieved if the interaction functions are radially unbounded and satisfy a sector bound condition. If the conditions are not satisfied, a local robust state agreement result is also developed.

According to the problem of UGVs' formation control in the process of motion, a formation control method of UGVs based on artificial potential field is proposed, established on the collision avoidance, aggregation and speed matching rules of UGVs. First establish the UGVs' kinetic model in accordance to the motion rules, then design the formation control algorithm based on artificial potential field function, which is used to control the formation during the movement of UGVs. Finally, the results of simulation and physical experiment verify the effectiveness of formation control method, which is also suitable for the formation control of large-scale UGVs.

Considering the privacy requirements on initial states for second-order consensus in wireless sensor and actuator networks (WSAN s), we focus on the design of one privacy-preserving second-order consensus (PPSC) protocol in a distributed way, and investigate this issue from both the viewpoints of limiting the kind of information to be broadcasted and adding random noises to the broadcasted information. We also investigate the convergence rate and the privacy level of the proposed PPSC protocol, and drive that if only limited information of one node is kept by its neighboring nodes, both its initial velocity and position states will be privacy-preserved. Finally, simulation results are presented to verify the effectiveness of the proposed algorithm.

The optimal soot blowing strategies of boiler systems with variable steam flow is investigated based on Hamilton-Jacobi-Bellman (HJB) equation in this paper. A continuous time Markov process with soot deposition mode and soot blowing mode is constructed as the mathematical model of boiler systems. In order to obtain the optimal soot blowing strategies, we propose a cost function based on the constructed boiler model, and derive the corresponding value function, which is the solution of HJB equation. In particular, the elementary properties of value function are described and proved strictly. Considering the difficulty of solving the HJB equation analytically, Kushner's method is applied to get the numerical solution of HJB equation, and the experiment results are analyzed.

In this paper, a modified adaptive feedback control scheme is introduced to ensure synchronization of two different fractional order chaotic systems with unknown parameters and different fractional orders. Based on the stability of fractional order system, a modified adaptive controller and an update law of parameters are developed. The proposed scheme is global and theoretically rigorous. One example is given to illustrate effectiveness of this method, in which the synchronization between fractional order Chen system and fractional order Qi system is successfully achieved. Corresponding numerical simulations are also given to verify the analytical results.

The study presented in this work explores the implementation of a watermarking scheme for quantum audio signals based on quantum Discrete Cosine Transformation (qDCT). The qDCT transforms the quantum host audio signal which is encoded as an FRQA (flexible representation of quantum audio) content from time domain to frequency domain and manipulates or modifies the high-frequency positions to embed the quantum watermark audio information into it. The strong energy compaction property of DCT is utilized in this scheme, i.e. after the DCT process to a digital audio, most of the signal information tends to be concentrated in a few low-frequency components and its high-frequency components could record some extra information like watermark audio. Built on the circuit model of quantum computation, the circuit networks to execute the embedding and extraction procedures of qDCT-based watermarking algorithm are designed and simulation-based experiments are conducted to demonstrate their implementation.

To improve the optimization performance of the TLBO algorithm for global optimization problem, an improved TLBO (ITLBO) algorithm with new learning scheme is proposed in this paper. In the learner phase, a no-best student learns from a random selected excellent student or an excellent student learns from teacher again according the fitness of the two mutual learners. To evaluate the performance of the proposed ITLBO algorithm, comparison with TLBO algorithm, several TLBO variants (A- TLBO, WTLBO, OTLBO, TLBO-GC) for the problem is carried out. Finally, Numerical results show that the proposed algorithm is an effective method for global optimization problems.

Aiming at the problems of demanding high frequency sampling devices and the factor hidden markov model algorithm without considering the correlation between the power equipments' running states, a novel non-intrusive load monitoring and decomposition (NILMD) method which based on factor hidden markov mode is proposed in this paper. This method considers appliances' current as load feature, and establishes a mathematical model between the total current and the currents of each appliance that considers the correlation between the running states of the equipment. Then, factor hidden markov algorithm is applied to search the running states of each appliance that realizes the decomposition of power load. The experiment shows that the resolution precision of each electric equipment is improved, and the principle of the method is simple. Meanwhile, the load data required in this method can be obtained directly by the universal smart meters on the market which reduces the cost input of the hardware.

This paper proposes two methods to describe the actuator amplitude and rate constraints with nested saturation function. The dynamic model of aerostat in the horizontal plane is established, and then the three order nested saturation controller is designed based on the nested saturation function. And as a result, the amplitude and rate of the actuator output are limited by the amplitude constraints of the nested function and the effectiveness of the control law is verified by simulation. The control quality is guaranteed by the state feedback controller. The advantage of the method is that the controller is simple and has strong ability to suppress disturbance.
