The new SFDIA scheme has a more reliable redundancy based on the FCC NN. The performance of the SFDIA scheme is validated by experiments of quadrotor with two gyro sensor modules.

The character or numeral image captured by a digital camera is converted to binary image. The character and numeral features extraction method is performed that consists of edge contour detection, thinning, and searching for coordinates of character and number. Then its coordinates is normalized and the DCT coefficients in horizontal and vertical components of coordinates are calculated. Finally, the impulse response of FIR system of that character and number is determined by setting the DCT coefficients in horizontal and vertical components as input and output of FIR system, respectively. The aim of this research is to apply the proposed concept to identify and recognize the characters and numbers on Thai license plate. On experiments, 100 car images are tested to identify the characters and numbers of plate number on Thai license plate.

To perform these operations precisely, the robots must possess good accuracy and repeatability. For that reason, all the industrial robot manufacturers and users are focused on the performance test of the robots using laser tracker. However, robot calibration is needed to precisely align the robot to the sensor and the world coordinate system to get accurate data of the accuracy. It also useful to identify an accurate kinematic robot model. The general idea of calibration is to measure n points in space while storing the joint data for each measured point. Using the joint data the forward kinematics can be calculated to obtain a target position of the robot. The calibration algorithm them starts tweaking the kinematic parameters of the robot such that the measured points are optimally fit the points provided by forward kinematics.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121532291","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}

The second plant was a large industry oven with a 0.125 m3 capacity, capable of exuding 1500 W of heat. Both experiments were controlled by the same Block Command and ovens were tested separately. The Cohen-Coon PID tuning method was firstly applied to both plants, with a separate controller values being obtained for each plant. These values were kept fixed throughout the experiments. A tailored approach was adopted whereby a pulse gen was used in conjunction with the PID control for the small plant; whereas a control zoning was used for the larger plant.

For the successful operation of the lunar rover, a high-accuracy navigation technique has to be obtained. In order to perform high-accuracy inertial navigation, the accuracy of initial alignment is important. In general, initial alignment can be divided into two processes, coarse and fine alignment. In the general coarse alignment process, the acceleration and rotation rate of the stationary rover are used as reference vectors. However, the acceleration and rotation rate of the Moon are 1/6 and 1/27 times smaller than those of the Earth, respectively. As a result, even though the same sensors are used, the performance of initial coarse alignment gets worse on the Moon. In this paper, three coarse alignment methods using accelerometers and sun sensor, instead of accelerometers and gyros, are proposed and the associated errors are analyzed. For comparison, the existing general coarse alignment algorithms are summarized. The analyses are verified by appropriate computer simulations, and it shows that the proposed algorithms greatly improve the performance of coarse alignment, outperforming the existing algorithms at least on the Moon. Therefore, the proposed algorithm is suitable for lunar rover application, and can also be applied to other planetary explorations.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126447011","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}

The cooperation concept is proposed to check an available space in the target lane for lane change in a short period of the future. Before moving to the target lane, the ego vehicle needs to check whether the object vehicle is cooperative or not for the lane change. The object vehicles are indexed as cooperative driver (CD) or non-cooperative driver (NCD) through the conditions based on the relative longitudinal acceleration and the collision free time. If the object vehicle is CD, the ego vehicle moves toward the target lane within the original lane for the preparation of the lane change. The ego vehicle should keep its lateral position within the original lane until the situation for the lane change becomes safe. As soon as the risk assessment becomes safe, the lane change is performed. Therefore, lane change can be started in advance compared to the conventional methods. The proposed method was validated via computational simulation and experimental results.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125306503","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}
