A more sophisticated method is proposed to adjust the adversarial bonus to promote learning efficiency instead of the linearly decayed scheme in adversarially guided actor-critic. Our method considers the relationship between the bonus adjustment and the learning procedure. In some environments, if an agent performs better in learning, the agent will reach the goal with fewer steps. If the length of the episode decreases, the adversarial bonus will be reduced in our method. In this way, the learning efficiency has been improved in some procedurally generated tasks. Several experiments are implemented in MiniGrid to verify the proposed method. In the experiments, the proposed method outperforms the existing adversarially guided methods in several challenging procedurally-generated tasks.","PeriodicalId":272227,"journal":{"name":"2022 37th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122406359","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}

Our method is a point-wise based method which could preserve the spatial information of point cloud and require low computation cost compared with mutil-view based methods and volumetric based methods. Point cloud is unordered and unstructured, making it challenged to design a point cloud method based on deep learning. The irregular format of point cloud makes typical convolution network can not be directly intended for point cloud classification. Our method utilize symmetric pooling module to capture context information among points which could better extract features. The channel & spatial attention mechanism is used to aggregate spatial information and enhance features of point cloud, which could improve the representativeness and accuracy of the whole network. We carrry out experiments on ModelNet40 and compare our method with other advanced point cloud classification method to testify the effectiveness of our method.","PeriodicalId":272227,"journal":{"name":"2022 37th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122444274","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}

In this paper, the bandwidth method is used to simplify the design of ADRC and the parameters are set. The control effect is verified by bus jump and load jump. The simulation is carried out in Simulink, and the experimental platform is built to verify the scheme.

Recall that the average consensus algorithm is generally adopted for distributed fault detection, which would inevitably result in detection delay. To deal with this issue, an alternative iterative approach is developed to achieve the optimal detection in each iteration step in this paper. To be specific, covariance coefficient matrix in the iterative process of the average consensus algorithm is first decomposed into the matrix product with the same structure, which lays the foundation for further distributed fault detection. Based on it, a distributed data-driven optimal fault detection is developed which consists of the offline training and online detection. In the offline training stage, the detection statistic function is constructed through the obtained covariance in the iterative fashion. In the online detection stage, the optimal fault detection scheme is carried out to solve detection delay problem in the iterative process of the average consensus algorithm. A case study on the Tennessee Eastman benchmark are used to demonstrate the proposed approach.","PeriodicalId":272227,"journal":{"name":"2022 37th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128970889","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}

There is an urgent need to promote the construction of distributed renewable energy power stations on the premise of safe and stable operation of power grid. Guided by the consumption of renewable energy, guide the optimization of layout and orderly integration. The existing research results in the world are mainly divided into two categories: dynamic simulation method and mathematical optimization method. Neither of the above two methods has the actual computing power of the whole network distributed renewable energy accommodation capacity. The accommodation capacity of distributed renewable energy connected to the power grid is restricted not only by the security of distribution network, but also by the overall consumption capacity of renewable energy main network. If the renewable energy absorption capacity of the main network is not considered, the grid connection of distributed renewable energy beyond the penetration limit would inevitably lead to insufficient peak shaving capacity or transmission congestion of the main network, further aggravating the phenomenon of centralized renewable energy. In addition, the calculation of the renewable energy consumption capacity of the main network has not taken into account the power flow constraints of the transmission lines in the province and the safety boundary of the distribution network. Therefore, the calculation results of the consumption capacity on the accommodation capacity cannot be obtained by dimensionality reduction. Therefore, only by comprehensively considering the factors such as distribution network security constraints, main network absorption capacity and main network power flow constraints, can the accommodation capacity of distributed renewable energy be scientifically and reasonably evaluated.","PeriodicalId":272227,"journal":{"name":"2022 37th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114809097","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}
