this paper proposes a data-driven-based distributed security control approach for vehicle-following platoons in the presence of denial-of-service attacks. First, distributed resilient observers are designed to estimate the trajectories of the leader-vehicle. Based on the developed observers, data-drivencontrollers are proposed for the vehicle-followers. Specifically, a datadriven approach is introduced to identify controller parameters without relying on the knowledge of system dynamics. Finally, a vehicle-following platoon example is provided to demonstrate the effectiveness of the data-driven-based distributed security control method.

As the condition of iterative learningcontrol, it is usually necessary to estimate the parameters of the system model to determine whether the system satisfies the global Lipschitz condition and estimate the upper and lower bounds of the rate of change of the system. However, for systems with unknown dynamics, the data-driven iterative learningcontrol based on system input and output cannot be realized fully. In this paper, using the nonlinear mapping and feature extraction ability of deep learning, only input / output data is used to determine whether the uncertain system satisfies the global Lipschitz condition and estimate the upper and lower bounds of the system's rate of change, so as to realize the iterative learningcontrol of the system. the simulation results verify the validity of estimating whether the system satisfies the ILC condition only based on the input / output data of the system.

this paper developes iterative learningcontrol scheme and the stability conditions for multiple time-delays discrete system. By formulating the problem over repetitive process form using 2D theory, sufficient stability conditions for multiple timedelays discrete system are developed along the trial, which guarantees the trial-to-trial error monotonic convergence. Moreover, the generalized Kalman-Yakubovich-Popov (KYP) lemma allows the iterative learningcontrol scheme to develope stability conditions with LMI constraints and analyze in the finite frequency domain. A numerical simulation for multiple time-delays discrete system is given to verify the proposed method.

Fault diagnosis is an important branch of modern control system and plays an important role in industrial production. Researchers keep pursuing more convenient and practical methods for fault diagnosis. As data collection becoming more convenient, data-driven methods develops rapidly for their excellent performance, especially the deep learning methods have been a popularity way to fault diagnosis. this paper tries to use two data-driven methods (ResNet-50 and SE-ResNet-50) on fault diagnosis without transfer learning. More uniquely, training data and testing data are collected under different conditions. SE-ResNet-50 achieves the highest accuracy 99.1%, which is better than ResNet-50 obviously. this experiment shows that SE-ResNet-50 achieves good performance without large training samples in fault diagnosis.

this article focuses on the iterative learningcontrol problem of a class of linear parabolic distributed parameter systems, which has the characteristic that the boundaries of the spatial domain change continuously with time. then, the open-loop P-type iterative learning method is used to study the system output tracking problem. through rigorous theoretical analysis, some methods such as the contraction mapping approach and Bellman-Gronwall inequality are used to prove the convergence of the tracking error. Finally, the effectiveness of the algorithm is verified by numerical simulation.

Withthe development of science and technology and the expansion of intelligent manufacturing technology, there are more and more automatic production lines in China, but the overall structure of the automatic production line is complex and the R & D investment cycle is long, resulting in low production efficiency. From the point of view of automatic production line structure and data virtual simulation, this paper studies the simulation control debugging system of automatic production line driven by PLC data. According to PLC data, the developer can carry out virtual commissioning of automatic production line and verify the timing of production line.

In this paper, a data-driven high-order model-free adaptive iterative learningcontrol (HMFAILC) is developed by a wheeled mobile robots (WMR) for trajectory tracking in the repetitive systems. the design and analysis of the controller only uses the I/O of the system and in the absence of any explicit model information. control performance is improved by using higher-order learningcontrol methods to obtain more control information in the iterative process. the control performance of the control scheme is proved by mathematical analysis and simulation.

In this paper, the dynamics of a flapping wing micro aerial vehicle is analyzed. Aiming at the difficulty of controller design caused by the nonlinearity, time-varying and strong coupling characteristics of the micro aerial vehicle, a full form dynamic linearization based model free adaptive control scheme (FFDL-MFAC) is presented to realize the pitch control of the controlled vehicle. In addition, a compensator is introduced to overcome the control input saturation caused by the limitation of the actuator. Simulation results are provided to demonstrate the effectiveness of the proposed MFAC.

In this article, a model-free-adaptive-control-based (MFAC-based) event-triggered (ET) consensus output tracking problem for multiagent systems (MASs) is investigated. the dynamic models of agents are unknown, and only a subset of agents can acquire the reference trajectory. the consensus tracking algorithm is designed by the real-time input/output data and pseudo-partial-derivative (PPD), which is an important parameter of MFAC approach. An output observer is built to design the centralized ET mechanism. then, the boundedness analysis that the tracking error is uniformly ultimately bounded (UUB) is given. Finally, a simulation experiment is provided to verify the feasibility of the ET consensus output tracking strategy for MASs.
