In this proposed algorithm, the global-level multi-robot cooperative formation control problem is decomposed into a tracking problem of some subsystems each of which only includes one follower and one lead robot. A multi-step predictive strategy is adopted, in which each follower predicts the motion of the leading robot and estimates the relevant information based on the history motion information. The follower keeps formation by observing its leader on the local coordinate system of the following robot. The simulation results are given to demonstrate the feasibility and effectiveness of the approach.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126153031","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 multivariable control structure is proposed to provide an extension of single channels. The control algorithm is performed on a rigid body dynamics in the form of vector states which are the velocity vector and the angular velocity vector in a body-fixed coordinate frame to ensure the states of the system are driven towards the expected manifolds exponentially in spite of the presence of perturbations, i.e., parametric uncertainties and external disturbances, and stay there for all future time.

Aiming at the problem, this paper proposes a distributed computing scheme that combines edge computing and cloud computing to improve power system data processing capabilities and system response capabilities. Besides, the paper analyzes the finiteness of edge node computing ability. According to the task load balancing theory, a task performance minimization as an objective function is proposed, and a high-performance load balancing strategy for immune chaotic particle swarms algorithm (ICPSO) is proposed based on this distributed computing architecture.

In this paper, we address the two tasks: people counting in images of highly dense crowds and pedestrian flow statistics in a place over a period of time. Our first contribution is to propose a new convolution neural network (CNN) model which is composed of a deep and shallow fully convolution network to fulfill the task of people counting. We extract different layer features from the deep fully convolution network and the last layer features from the shallow fully convolution network, and concatenate them together. After that we add two deconvolution layers to make the output image have the same resolution with the input image. Our second contribution is to combine pedestrian flow statistics task with people counting task. According to the density maps that CNN model generates, we can calculate the number of people crossing a place based on the recurrent neural network (RNN). Besides, we also have collected two datasets and labelled them. Extensive experiments have been implemented, our people counting method outperforms other existing methods, and our pedestrian flow statistics method combined with CNN model also outperforms the model which only uses long-short term memory (LSTM).","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127401216","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}

PHEV may consume electricity while charging, may supply electricity while discharging, and may serve as a storage to the electric power grid. It is therefore of significant practical interest to coordinate PHEVs with the rest of the grid. Supply demand coordination is an important way to achieve high energy efficiency at the system level while satisfying the stability of the grid and the trip requirement of the PHEVs. This problem is challenging due to the highly uncertainty from both the supply and the demand side in the system, the multiple-stage decision making, the large-scale of the system, the multiple objective functions and constraints involved. In this work, we briefly review the recent development in this field. We hope this work may shed some insight on supply demand coordination in vehicle-to-grid in general.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"363 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114500790","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}

As one of the main components applied on controlling the wind turbine nacelle position in parallel with the inflow wind, it directly determines the maximum available wind energy to capture. However, the inherent misalignments on yaw error caused by improper calibration of the wind vanes during wind turbine installation, are usually severe and impact on the performance of yaw control strategies. In this study, a data-driven inherent misalignment identification and compensation scheme for yaw error is proposed. The real-time data from turbines are collected and a power generation curve is located for each yaw error interval. Subsequently, multiple power curves are evaluated via output performance indicator analysis for determining the actual inherent misalignment value. The entire system is implemented and testified with the SCADA data collected from real wind turbines.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128913204","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}
