Title: Key Technology and Equipment for USV

Abstract: Unmanned surface vehicles USV) have found extensive applications in mapping nautical charts, investigating marine environment, and supporting national military defense. USVs that are at abominable sea states are faced with crucial challenges including how to navigate accurately, how to automatically avoid obstacles, how to get retrieved by carriers and how to stay stable. Hereby we propose an anti-disturbance control method based on space mapping between flow disturbances and USV attitude. As such, high-precision trajectory tracking is achieved in complex areas of reefs, islands and coral cays. Under code 4 sea state, the tracking error is within 2m, which is 60% more accurate than that IHO Standards for Hydrographic Surveys (5m+5%d). We propose a control method based on uncertainty set constraint for obstacle avoidance, achieving a safety distance as short as 40m away from moving target at sea under the high speed of 18kn. Also, we develop vibration isolation technique based on a 6 DoFs fully decoupled mechanism, nonlinear negative stiffness rheological structure and a large-amplitude-single-frequency vibration control approach. The amplitude and stabilizing period are sharply reduced by 98.4%, and from 7s to 0.3s, respectively. The USV vibration at sea is suppressed to -10dB@1HZ and -35dB@10Hz, achieving the sound stealth effect. With the above combined technologies, our USVs managed to accomplish a great many tasks, e.g. mapping charts, undertaking geological survey, conducting sea rescue, investigating marine environment, implementing archaeological survey and so on at East China Sea and South China Sea.

Title: Distributed Cooperative Fault Detection for Multi-Agent Systems

Abstract:Multi-agent systems have received more and more attention because of their many advantages such as low development cost, high efficiency and flexibility. However, the lack of a central agent to monitor the entire system's behavior makes the system extremely vulnerable to interference, trapping and strikes, which may leads to faulty nodes and brings great challenges to the security and reliability of the system. In this talk, we propose a novel distributed fault detection scheme where the cooperation mechanism among agents is applied to achieve reliable detection of faulty agents without improving the hardware performance of agents. This scheme can solve the fault detection and identification problem under the condition that both physical faults in facilities and false-data-injection attacks in communication networks exist, and can also solve the fault detection problem using only relative output measurements. Moreover, a data-driven fault detection algorithm by using both hardware redundancy and time redundancy is investigated.

Title: Convergence of distributed estimation algorithms of multi-agent systems

Abstract: With the development of computer science and communication, sensor networks are widely applied due to the advantages of flexibility, fault tolerance, and ease of deployment. The sensor networks bring more and more data, and how to apply the data from the sensors to design the proper estimation algorithm is a promising research direction. The distributed estimation algorithms are proposed where the distributed estimators are aimed to collectively estimate an unknown parameter from a set of noisy measurements obtained by distributed sensors. The cooperative excitation conditions are introduced, under which the convergence of the distributed estimation algorithms can be obtained without relying on the independency and stationarity assumptions of regression vectors which are commonly used in existing literature. Furthermore, we show that all sensors can cooperate to fulfill the estimation task even though any individual sensor not.

Title: Delay Feedback Control for Switching Diffusion Systems Based on Discrete Time Observations

Abstract:For the sake of saving time and costs the feedback control based on discrete-time observations is used to stabilize the switching diffusion systems. Response lags are required by most of physical systems and play a key role in the feedback control. The aim of this paper is to design delay feedback control functions based on the discrete-time observations of the system states and the Markovian states in order for the controlled switching diffusion system (SDS) to be exponentially stable in pth moment and probability one as well as stable in H_∞. The designed control principles are implementable to stablize

quasi-linear and highly nonlinear SDSs. For quasi-linear SDSs the criteria are sharp that under the control with high strength the controlled SDSs will be stable (bounded) while under the weaker control they will be unstable (unbounded) in mean square. The sample and moment Lyapunov exponents are estimated which have close relationship with the time delays.

Title: Control and analysis of stochastic high-order nonlinear systems

Abstract:Stochastic high-order nonlinear systems is an important class of stochastic systems including stochastic underactuated mechanical system as a special case. Due to the Jacobian linearizations of such systems are neither controllable nor feedback linearizable, with the effect of stochastic noise, the control and analysis is nontrivial.

Stochastic homogeneous domination technique and distributed integrator backstepping design method are developed.
