| Noncontact suspension is achieved with three flux-path control mechanisms placed in the lateral of a magnetic source (permanent magnet). The attractive force acting on a ferromagnetic suspended object (floator) is adjusted by moving the ferromagnetic control plates vertically beside the permanent magnet. Such a configuration enables the effective gap to be larger than in the conventional flux-path control magnetic suspension system. An apparatus with three flux-path control mechanisms is designed and fabricated. In this mechanism, a ferromagnetic control plate is fixed on one end of a lever. |

Position Control of Brushless DC Motor using Adaptive Sliding mode Control |
|
Jinsuk Choi(POSTECH, Korea) |
| In this paper, we propose position control method using adaptive sliding mode control (ASMC) with timedelay Control (TDC) for Brushless DC motor (BLDC). PID control for position control of the BLDC cannot satisfy control need for disturbance and uncertainty in nonlinear systems. The BLDC position is controlled by applying ASMC with time-delay estimation(TDE) and pole-placement control (PPC). This controller solves the performance degradation due to the nonlinearity component of BLDC and improves performance in the transient state |

MOBILE APPLICATION FOR RECOVERING PARALYSIS PATIENT’S MOTION |
|
Anuntapat Anuntachai(King Mongkut’s Institute of technology Ladkrabang, Thailand) |
| Paralysis is a symptom when patient’s central nervous system is failure because of blood deficiency. The
patients cannot comfortably move their bodies due to muscle hyposthenia. The restoration requires regularly physical
therapy which needs high accuracy because muscles have dysfunctional. This thesis represents the mobile application
which help to muscle restoration of paralysis patient. This mobile application improves accuracy and efficiency of
physical therapy. The physical therapy and muscle operation principles are collected and analyzed by this mobile
application and iBeacons sensors. |

Use of Deep Learning for Position Estimation and Control of Soft Glove |
|
Jeesoo Ha(Korea Advanced Institute of Science and Technology, Korea), Dooyoung Kim, Sungho Jo(KAIST, Korea) |
| Soft wearable robots comprised of deformable materials have recently attracted much attention in the field of applications for its lightness and elasticity. However, there exist some limitation to the control of wearable robots due to
the complexity of the model and the conditions of the wearer. In this paper, we propose a learning-based position control method of soft wearable glove using a deep neural network (DNN). To analyze our proposed method, we fabricated a soft
pneumatic glove and a control board for the glove based on open hardware platform data. With our developed system, we collect |

Development of Compatible Induction coil with Pure AC for Hall Effect Sensor: A Study on Metal Materials Thickness |
|
Witsarut Sriratana, Yannadech - Khwankityotha, Sutham Satthamsakul(King Mongkut’s Institute of Technology Ladkrabang, Thailand) |
| This study presents an analysis of the parameters to generate the electromagnetic fields of the induction coils for the application of Hall Effect sensor to classify the aluminum thickness and the classification of the metal materials. In this research three types of induction coil are considered: Type A with one layer, Type B with two layers, and Type C with three layers. Four experiments were conducted. The electromagnetic field of Type C is found to be 11.90% greater than Type B, and 29.26% greater than Type A... |

Development of Sensor Module for Detecting the Magnetron Power Based on Microwave Oven Frequency |
|
Sutham Satthamsakul, Witsarut Sriratana(King Mongkut's Institute of Technology Ladkrabang, Thailand) |
| This study presents the design of sensor module to be used in analyzing the electromagnetic power created from magnetron by using microwave as the case study on basis of Rectenna (Rectifying antenna) consisting of 2 main parts including sensing part and transduction part. The experimental results would be used to analyze the appropriate form of sensor module. This research compared sensor module for 3 forms including Type A, Type B, and Type C, with different sizes of diameter of wires consisting, by comparing the efficiency in preventing the leak of measured power. |
