The elevator regenerative drives transform gravitational potential energy into electrical energy by utilizing elevators’ operation characteristics and weight difference between carriage and counterweights. The regenerative power is then fed back into electrical grid of a building and afford other electrical equipment to achieve energy saving. This paper investigates the operating principle of elevators, describe the mechanism of regenerating power, distinguish the terminologies of the power saving rate and the regenerative energy ratio, and finally use a power analyzer to monitor the experimental data of an elevator before and after installing a regenerative power drive.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"36 17","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120935071","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}

Mental arithmetic, mental counting, word formation, and mental rotation are used as brain task to generate the commands. The brain signals are decoded simultaneously in a single window using hybrid EEG-fNIRS. We extracted the neuronal and hemodynamic features in 0∼2 sec, 0∼2.25 sec, and 0∼2.5 sec windows. An overlapping window of 0.25 sec is used for online/real-time analysis. Signal peak, signal mean, and signal power are computed as features for EEG. Signal mean, signal slope, signal peak, and minimum negative value are computed as features for fNIRS. We used linear discriminant analysis to classify the features in online scenario. The generated commands are transferred to a quadcopter using Wi-Fi. The quadcopter movements are controlled by the transmitted brain commands. Our results showed that overall system accuracy for fNIRS was increased from 69% to 84 % by combining features with EEG. This enabled more stable control for the quadcopter. Therefore the result seems significant for brain-computer interface applications.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121929925","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 contrast to RTK method, a slightly perturbed integer value may incur large positioning error. To use carrier phase observations for positioning in PPP, it is necessary that the integer cycle is accurately fixed in order to have a highly precise location estimation. For these reasons, we proposed a new method to estimate the integer ambiguity. Firstly, SVD method is used to smooth the raw data, in which the code phase and carrier phase observations are both used. In this smooth process, some noise in the observations can be eliminated so that range of ambiguity search space is greatly reduced. We then estimate the floating point solution by using WLS method. Furthermore, in order to have more accurate integers, we proposed a modified LMS algorithm using a new cost function different from the existing method. From the results of the experiment, one can see that both sub-meters precision and accuracy are achievable using the proposed method.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127582154","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}

Thus, noise removal is a key technology for image processing. We choose four kinds of noise removal's methods to introduce. There are fuzzy logical, image fusion, artificial neural network, non-local means.

One of the possible solutions to overcoming the aforementioned difficulties is to introduce machine vision into the robotic arm system. In this paper, the eye-to-hand camera configuration is adopted in the development of the vision-based automatic pick-and-place systems for 3-D objects. The vision­based automatic pick-and-place system developed in this paper consists of three main sections — calibration of machine vision system, object recognition, and transformations of object coordinates.

In practice, the outputs of analog encoders are not the quadrature sinusoidal waves, in which there always are mean offsets, phase offsets, and amplitude distortion. In this paper, to calibrate these encoders, the calibration coefficients are introduced. These coefficients are obtained by the least-squares method to attenuate offsets and distortion of encoder outputs. MATLAB/Simulink are used to simulate the algorithm of signal calibration and a subdivision algorithm is given to improve the resolution of analog encoders. In the experiments, the algorithms are implemented and tested on the digital signal processor in a motor driver. Finally, through a servo motor driver, the motor can be controlled and performs well by using an analog encoder with feedback from subdivided signals.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"34 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120895271","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}

Initial conditions for shuffling and confusing stages are generated by the proposed authorization system after being provided by the user at the beginning of the process.

To improve the performance of the robots, it has been widely researched in robotics. In this paper, a general kinematic method for R-θ type manipulator is created using the combination of screw theory and dual-quaternion, it can be applied to different type of R-θ robot with different arm length. Screw theory provides a global geometric representation of the kinematics of manipulator which greatly simplifies the analysis of the mechanism and can avoid the singularities due to using local coordinates. With this method, the kinematics of the R-θ type manipulator is expressed by dual­quaternion representing the screw motion of each joint of the manipulator. By dual-quaternion only eight numbers are used to express a screw motion. Meanwhile, the motion transformation by dual-quaternion takes fewer calculations than the homogenous matrix. Thus, comparing with the traditional D-H parameter method, this method provides a compact, computationally efficient algorithm of kinematics of R-θ type wafer transfer robot which needs less storage space and does not suffer from singularity problem.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129545748","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}
