The motion of the mobile robot was accomplished by the differential drive mechanism with four driving wheels in which the overall velocity is split between left and right wheels. The two-channel DC motor controller was used to drive motors. The digital compass was used to calculate the position angle of the mobile robot with respect to the target point. A Kalman filter was used to fuse the information from GPS and digital compass. In the proposed algorithm, the mobile robot is driven in a straight line along a predefined path by calculating in real time the deviation angle difference with respect to the target point. When the robot encounters an unexpected external force varying the desired path, it achieves a smooth and stabilized straight line movement by correcting the deviation angle difference. The performance of the mobile robot was evaluated based on a total of 18 straight lines in a farmland. Standard errors of cross track error (XTE) values of straight lines for each target point were analyzed. The mean of arithmetic means was found to be 4.14 cm. The mean of R-square was 0.990. This value shows that the proposed angular correction algorithm is useful in driving the mobile robot in a straight line.

Especially the stop-and-go mobility seen in heavy traffic conditions was simulated with a mobile robot, and the study is focused on how to obtain distance-time trajectories more accurately under these conditions. System identification tests of the mobile robotic platform, whose kinematic model was developed, were also carried out, and all solutions regarding robot movement were obtained. For the congested traffic simulation, various stop-and-go points are designated on a predetermined straight route segment to mimic behavior of a vehicle in congested traffic. Robot trajectories were obtained under different scenarios by using both GPS data and a kinematic model through the utilization of motor encoders. More accurate and consistent trajectories were achieved by fusing these trajectories with the Extended Kalman Filter. The main contribution of this study is demonstrating how the number of stop-and-go positions can improve the accuracy in estimating the robot/vehicle trajectory. The paper shows how the cumulative error in predicting the trajectories in reduced as the number of stops increases. For example, the trajectory estimated for a scenario involving five stop-and-go points is 94% more accurate than that for the case with a single stop.

The polytopic model of closed-loop synchronization error dynamics is established by considering the pattern characteristics of false data injection attacks and input delays, which has essentially different from the traditional handling method. More specifically, the proposed polytopic model utilizes the current state of the closed-loop synchronization error dynamics, thereby facilitating the reduction of possible conservatism. In such a framework, a nonlinear synchronization control method is developed to eliminate the negative impact of cyber attacks, and sufficient conditions are derived to guarantee that the closed-loop error dynamics ultimately exponentially bounded. In the meanwhile, the design procedure of the synchronization controller is proposed for underlying complex cyber-physical networks subject to mixed delays and false data injection attacks. Finally, an illustrative example is delivered to demonstrate the effectiveness of the proposed method.

Low rank representation (LRR) has aroused much attention in the field of data mining. As a modified version, the low rank representation with adaptive graph regularization (LRR-AGR) exploits the global and local information of data for graph learning, and it simultaneously integrates distance regularization term, non-negative constraint and a rank constraint into the framework of LRR. However, how to balance these regularization terms according to the data greatly limits its clustering performance. To adaptively balance these regularization terms according to data and further improve the clustering performance, we propose a novel model named low-rank representation with adaptive parameters and graph regularization (LRR-APGR) in this paper. Firstly, a novel parameter optimization model is formulated and designed based on the framework of LRR-AGR and the feedback mechanism. Secondly, two global intelligent optimization algorithms, which can effectively solve the parameter optimization problem are presented based on particle swarm optimization (PSO) in multi-dimensional continuous space. Experimental results on the data oilsk81, oilsk83 and oilsk85 wells of Jianghan oil fields in China show that the proposed method can significantly improve the clustering performance and the predictive accuracy.

The exoskeleton is designed through the analysis of human's upper limb biomechanics and dynamics. Based on the requirements of human joint power, the solutions of mechanism and actuator for the exoskeleton are drawn. During development of the exoskeleton, a basic control hardware is built to ensure real-time control performance besides a custom-built control panel for users. A patient-oriented control strategy allows RAUPEX to assist patients with various disability level in rehabilitation. The robot's applicable efficiency has been evaluated through rehabilitation training tests on healthy persons as quasi-patients via fundamental criteria in the exoskeleton development. Normalized square sum of angular operator-exoskeleton errors that is $(25.3pm2.45)times10^{-3}$ for active control and is $(5.89pm0.42)times10^{-3}$ for passive control. Moreover, the resulting operator-exoskeleton interaction force which is maximum of $7.75$ N at upper arm and $4.32$ N at lower arm enables RAUPEX to accurately assist rehabilitation exercises without discomfort. Over $87%$ of experimental participants claimed to feel comfortable which proves the developed exoskeleton has the potential to increase efficiency and adaptation to users during rehabilitation procedure.

In case of overhead power lines, approximately 80% of the total registered faults have a transient character. Therefore, the management of transient faults is important because this has a direct consequence on the energy distribution process and has a large influence on the quality of energy supplied to consumers. The development of mathematical models of wide applicability, to accurately represent the propagation of a transient fault on the 110 kV lines is possible through data analysis recorded during real life events, which constitute a clear representation in time of an actual fault. The use of these mathematical models made it possible to reduce the detection time of transient faults, ensuring benefits in terms of reducing the extent of power outages, which leads to shorter recovery times. The proposed operating algorithm of the developed control structure for transient fault detection and line protection triggering allows the improvement of distance protection reaction in the event of a transient fault, to safely overcome critical moments in network operation, aspects that recommend the proposed solution for practical implementation.
