Control of Switched Asynchronous Machines with Application to Dual Counters |
|
SangSik Lee, Jung-Min Yang(Kyungpook National University, Korea) |
| Control of switched asynchronous machines with application to dual counters is investigated in this paper. The switched asynchronous machine, comprised of a set of different sub-machines, changes its mode to each sub-machine according to the switching sequence generated by the controller. All sub-machines are subject to the negative effect of adversarial inputs. The control objective is to design a state feedback controller so that the switched machine can recover the original state after going through unauthorized state transitions by faults. We propose a method of designing a corrective cont |

Development of a wearable soft sensor system for measuring finger motions |
|
Kyongkwan Ro, Suin Kim, Wookeun Park, Joonbum Bae(Ulsan National Institute of Science and Technology, Korea) |
| A wearable sensor system was developed to measure finger motions, which consisted of soft and stretchable silicone filled with the electro-conductive liquid metal, called eutectic Gallium Indium (EGaIn) alloy. Due to the light weight and highly stretchable properties of the silicone, the wearable sensor system allowed natural movements for the users, and it was able to adapt various hand sizes. In the proposed system, the flexion and extension of index and middle finger, and the abduction of index finger could be measured. |

| A high resolution yaw sensor employed widely for observation the small angle measurements and angular applications. It needs to calibrate with high accuracy of standard for achievement of their performance and traceability. The measurement uncertainty evaluation of yaw sensor calibration is also necessary. This paper presents the technique of measurement uncertainty evaluation of yaw sensor following the guide to the expression of uncertainty in measurement (GUM). The uncertainty evaluations were approximately minimized to 40 arcsec, the confident level approximately 95%. |

The Application of Yaw Sensor Measuring Carriage System |
|
Vittaya Tipsuwanporn, Wanchai Chinchusak(King Mongkut's Institute of Technology Ladkrabang, Thailand) |
| Laser interferometers have generally been used for the angular measurement of measuring tape calibration systems. Yaw error measurements using a yaw sensor have been carried out to determine the characteristics of yaw errors and analyze the behaviors of the structural guide. The yaw sensor technique is identical to the error compensation used in a measuring tape calibration, and also has some special parameters. However, the yaw error observation period is very short, but it is sufficiently accurate for a carriage yaw sensor. This paper presents the yaw sensor innovation for the measuring car |

Multi-point Fuzzy Prediction for Load Forecasting in Green Buildings |
|
Hsuan-Hao Chang, Wei-Yu Chiu(Yuan Ze University, Taiwan), Ting-Yen Hsieh(Industrial Technology Research Institute, Taiwan) |
| A novel load forecasting mechanism that uses fuzzy logic and big data, termed multipoint fuzzy prediction (MPFP), is proposed. The prediction mechanism is based on historical data and, therefore, is adaptive to dynamic changes over time when the database is updated properly. An energy management system (EMS) can be integrated into the framework to achieve an improved level of performance. On the basis of a prediction of load curves, the EMS can discharge energy storage devices when electricity prices are high and charge them when electricity prices are low, reducing costs.
