this paper considers the optimal consensus of multi-agent systems using reinforcement learningcontrol. the system is nonlinear and the number of agents can be large. the control objective is to design the controllers for each agent such that all the agents will be consensus to the leader agent. We use the Actor-Critic Network and the Deterministic Policy Gradient method to realize the controller. the policy iteration algorithm is discussed and many simulations are provided to validate the result.

A solution to the interference of control signals and signal loss in the process of signal transmission in the process of decentralized model predictive control (DMPC) is introduced in this paper. Judging whether the data packet is lost at each time sampling signal, then the approximate value of the lost signal at this time is calculated in an alternative way. the results show that: this method is feasible.

this paper presents a design method of repetitive learningcontrol for a class of nonlinear uncertain systems. the control design is carried out by the estimation of the desired control and the norm-bounding uncertainty. By the adaptive learning techniques, the desired control is taken as a parametric uncertainty with regressor one. In addition, the variation of the nonlinearity, characterized by the bounding function, can be handled to alleviate the requirement for the knowledge about the system dynamics. the upper bound of the control gain is only required in this scheme. the boundedness of variables in the closed-loop system and the asymptotical convergence of the tracking error are established. And numerical results are presented to demonstrate the effectiveness of the proposed control scheme.

this paper investigates the consensus tracking problem for a class of multi-agent systems with measurement saturation and random noises. A distributed iterative learningcontrol algorithm is proposed by utilizing the input signals and the measured output information from previous iterations. the considered multi-agent systems have a fixed topology of the communication graph and the desired trajectory is only accessible to a subset of agents. Withthe help of a decreasing gain sequence, it is proved that the input sequence will converge to the desired one in an almost sure sense as the iteration number goes to infinity. Simulation results are given to verify the effectiveness of the proposed algorithm.

In this paper, a data-based iterative learningcontrol (ILC) is developed to address the output tracking problem of continuous-time locally Lipschitz nonlinear systems subject to input saturation. Under a data-based ILC update law with saturation, an extended datadriven framework is established for the ILC convergence in the presence of locally Lipschitz nonlinearity and input saturation. A relative degree condition and the input-to-state stability are given to ensure the boundedness of the state and the convergence of the output tracking error simultaneously. the simulation demonstrates the effectiveness of the results.

this paper deals withthe problem of sampled-datacontrol for T-S fuzzy systems with quantized signals. Based on the constructed Lyapunov-Krasovskii functional(LKF), Jensen's inequality and Free weight matrix, some sufficient conditions are obtained in the form of linear matrix inequalities(LMIs). By combining the input delay approach and dynamic quantizer, the sampled-datacontroller is designed to guarantee that T-S fuzzy systems with quantized signals is asymptotically stable. Finally, a numerical example is presented to verify the feasibility and effectiveness of the proposed methods.

this paper researches iterative learningcontrol for a class of singular systems with randomly iteration varying lengths. Based on an equivalence decomposition of discrete singular systems, a new learning algorithm with a stochastic variable and moving average operator is used to cope withthe state tracking problem under non-uniform trial lengths circumstance. the stochastic variable is included both in tracking error and control input. Furthermore, the convergence condition of the proposed learning scheme is put forward and strictly proved. In the end, a numerical example is presented to demonstrate the effectiveness of the theoretical results.

this paper focuses on the leader-following consensus control problem of nonlinear multiagent systems. the fuzzy logic systems are used to approximate the system uncertainties from the unknown nonlinear dynamics, and a novel adaptive fuzzy controller is presented by combining the Lyapunov-Krasovskii functionals. Withthe help of Lyapunov-Krasovskii functionals the state-delay of systems is compensated. A major advantage of the proposed adaptive consensus method is that it can greatly reduce the computation burden. Finally, one simulation example is given to verify the effectiveness of the designed algorithm.

the drawback to Typicality and Eccentricity data Analytics(TEDA), a classic unsupervised learning algorithm, is that TEDA requires strict priori knowledge during the stage of data preprocessing. In view of the disadvantage, a method of unsupervised fault detection called Laplacian Score with TEDA (LS-TEDA) is proposed. Features are selected by LS and unsupervised fault detection is realized by using TEDA in this method. LS-TEDA has been applied with Lublin Sugar Factory and the result shows high accuracy in fault detection.

In this paper, the fault estimation issue is investigated for a type of nonlinear stochastic repetitive systems using the iterative learning (IL) approach. Different from the existing works, a type of systems with initial state errors, stochastic disturbance and measurement noise is considered. In order to estimate the fault, a novel nonlinear iterative learning observer (NILO) is designed by using previous input signals and output estimation errors. A necessary and sufficient condition is obtained to guarantee the uniform ultimate boundedness of fault estimation errors in terms of lambda-norm withthe given IL strategy. Finally, the given approach is verified by a simulation example.
