With the development of economy, the social electricity situation is increasingly complicated, which brings great test to the prediction of electric load system.

Aiming at the above problems, this paper proposes a coordinated control algorithm that can track the desired trajectory of the end-effector based on a class of 5-DOF mobile manipulators. The algorithm takes the power consumption and trajectory stability of the entire system as the optimization objectives, and sets the function of the selected optimization objective on the desired trajectory, and performs optimization based on the interior point method of convex optimization to converge to the optimal solution faster. Finally, the system is simulated to verify the correctness and effectiveness of the control algorithm.","PeriodicalId":287137,"journal":{"name":"2022 China Automation Congress (CAC)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129290325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through the investigation of copper processing plant, we found that workers have little safety awareness, who often get into factories without helmets and enter non-safety areas without permission. To prevent safety accidents, we propose a multi-task model to detect some unsafe behaviors based on computer vision techniques. The model is composed of a shared encoder and two independent decoder branches. It can be used to detect the safety helmet and the factory landmark lines at the same time. According to the detection results, it can be judged whether the workers regularly wear the safety helmet or they are in the unsafe area in real time. Through the judgment of workers’ safety status, we can strengthen the safety supervision of industrial site, which has strong practical significance and application prospect.","PeriodicalId":287137,"journal":{"name":"2022 China Automation Congress (CAC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123919586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A hierarchical least squares method is proposed to estimate model parameters and track disturbance in combination with auxiliary modelling strategies and separable techniques. The multi-innovation technology for error updating is used to augment the dimension of the innovation matrix, in order to reduce the estimation error variance and enhance the convergence stability of the algorithm. The time-varying disturbance is still tracking by a single innovation strategy. Two adaptive forgetting factors are proposed to enhance the system parameters' convergence characteristics and to improve the track ability of time-varying disturbance. An example is applied to validate the benefits of the proposed algorithm.

Traditional algorithms lack environmental assessment model, train quality, and indicator function in the adversarial environment.

Then, an indicator function and an evaluation model considering the miss distance, threat situation, and the number of specified interception targets are introduced into the reinforcement learning algorithm. The local and global reward functions are introduced to improve the training convergence and efficiency in the multi-missile multi-target confrontation scenario.

There exist some practical NPCs in service, whose pressures are mostly controlled using the conventional PID controller with parameters regulated by engineering methods. Until now, there is no report about the model of NPC system from the authors’ best knowledge. In this paper, the model of the NPC system is reported, which is an inherent nonlinear system. Because of the nonlinear nature of the cabin pressure, the conventional PID controller cannot achieve desire performance to balance the transient and the steady state performance, even though the optimized PID parameters are chosen using the on-line optimization based on genetic algorithm. To solve such a problem, Tracking Differentiator (TD) and PI controller are combined to achieve the desire performance using the optimized parameters. The experiment results show the improvement of the proposed method.","PeriodicalId":287137,"journal":{"name":"2022 China Automation Congress (CAC)","volume":"307 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123234965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the original target box in YOLOv5 network which was not suitable for this detection task is improved, and the clustering method of target box obtained from the original network was optimized to K-Means++ clustering method to generate new anchor coordinates. Secondly, the CSP structure of YOLOv5 network was replaced by the CSPGhost structure composed of Ghost module. The CBAM attention mechanism module is added behind the backbone network to improve the image feature extraction ability of the network model. Finally, the detection layer structure of the model is improved, and the detection scale of the target is increased to improve the detection accuracy of the model for small targets. In order to verify the effectiveness of the improved network, a model comparison experiment is designed in this paper. It shows that 45 types of traffic signs are detected on TT100K traffic sign dataset.

The implementation of strategies has gradually expanded from a single field to multiple fields. These changes improve quality of products, innovation ability and efficiency of resource allocation of manufacturing systems. In recent years, reducing energy consumption has become the focus of both industry and academics. In order to save energy, we consider switching on/off a machine in the production lines when certain thresholds of buffers are reached. In this paper, we investigate Bernoulli serial lines with buffers having limited capacity which run finite production. Mathematical model of the three-machine line which produce finite products is established and analytical methods of calculating production rate, consumption rate, blocking probability, starvation probability, completion time and energy consumption are proposed. Markovian approach is adopted in three-machine lines analysis. Meanwhile, simulation is used to analyse serial lines that have numerous machines.","PeriodicalId":287137,"journal":{"name":"2022 China Automation Congress (CAC)","volume":"125 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120886514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
