Parallel robot is a highly nonlinear system with closed-chain mechanisms, which poses the major challenges to the controller design. The robust sliding mode controller is developed to deal with system uncertainties such as modeling errors, frictions, and disturbances. With strong adaptation and learning ability, RBF neural network is adopted to identify the parallel robot dynamics, and then the adaptive self-tuning of the control gains in the controller is realized, which is more flexible than manual tuning method and can guarantee the desired results of the changing system. The stability of the controller has been validated using Lyapunov theorem. Simulation results demonstrate that the proposed controller can achieve better tracking performance than the sliding mode controller with fixed control gains.","PeriodicalId":125740,"journal":{"name":"IECON 2022 – 48th Annual Conference of the IEEE Industrial Electronics Society","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125617202","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}

El-Bab","doi":"10.1109/IECON49645.2022.9969048","DOIUrl":"https://doi.org/10.1109/IECON49645.2022.9969048","url":null,"abstract":"Temperature control is vital in micro-heaters used in medical devices such as the polymerase chain reaction (PCR). The primary goal is to achieve tight control and a high rate of heating for a portable, low-cost medical device. Even though the fact that several designs for micro-heaters have been proposed, uniform temperature distribution and the high-speed heating rate remain challenging for micro-heaters. This high speed is achieved by the reduction of the thermal mass. The most common methods for reducing thermal mass or heating time in a device are to establish a highly desired structural design and to select a better heating mechanism with a robust controller. Increasing the thermal mass improves temperature distribution on the heater surface but slows heat transfer. On the other hand, removing the thermal mass makes the controller struggle to provide a high-temperature uniformity distribution on the micro-heater surface. In this study, we provide a design of a cost-effective, high-speed, thin-film micro-heater based on the Joule heating technique. The CoventorWare software tool is used to simulate the temperature distribution of the micro-heater. The heater provides a well-distributed temperature on the heated surface. When a DC voltage of 24 V was applied for 250 s, a maximum temperature of 272 °C was obtained. Besides, the heater’s average heating rate is 15 °C/s. The heater is then fabricated with the micro-electromechanical systems (MEMS) technology on a silicon substrate. The transfer function of the heating system is computed. Two controllers are designed to control the temperature of the micro-heater and improve its response. The classical proportional–integral–derivative (PID) controller produces rise time (Tr) of 21.9 s, settling time (Ts) of 73.3 s, and a maximum overshoot (Mp) of 4.8 %. Then by applying a fractional-order proportional-integral-derivative (FOPID) controller, a great enhancement in the system performance is observed, the controller is faster than the normal PID controller, the rise time (Tr) reaches 16.4 s and the settling time (Ts) reaches 23.6 s. It also reduces the maximum overshoot (Mp) to 0.32 %.","PeriodicalId":125740,"journal":{"name":"IECON 2022 – 48th Annual Conference of the IEEE Industrial Electronics Society","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122240524","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 the literature, leakage inductance calculation at medium frequency is analyzed considering the effects of eddy currents, winding arrangement, etc., but the effect of winding material remains unexplored. This is analyzed by calculating the magnetomotive force (MMF) distribution in the winding volume for different conductor materials. This helps deduce the energy stored in the winding and thereby formulate the effective leakage inductance analytically. Moreover, conductor materials with different resistivities exhibit different temperature coefficients. Therefore, this study also investigates the effect of temperature rise in the windings on the effective leakage inductance due to the change in the wire resistivity. Finally, a comparative analysis between Al and Cu foil designs of a 16 kVA, 1.5/20 kV, 20 kHz transformer is presented to summarize the relative benefits of using Al foils for high power MF transformer designs. The analytical model is verified using 2D FEM analysis. This study shows that higher resistivity material leads to higher leakage energy stored in the conductor volume; consequently this helps achieving higher leakage inductance. As the material resistivity increases with temperature, this also leads to higher leakage inductance.","PeriodicalId":125740,"journal":{"name":"IECON 2022 – 48th Annual Conference of the IEEE Industrial Electronics Society","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115830004","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}

It should extend network lifetime and guarantee network sustainability and reliability. Charging from one energy source (ES) shared by several WDs makes the scheduling algorithm most important. This paper considers a directional ES that has significant scheduling impacts relative to the more commonly studied omnidirectional ES. The directional energy source overcomes the restrictions of broadcast energy by concentrating the power on the intended sectors and thus significantly improving energy efficiency. We propose a charging scheduling algorithm to maximize the network lifetime under several network conditions. The proposed algorithm first determines the charging duration for all WDs in a given sector. The algorithm then determines the transmit power from ES to each WD in the sector. The performance of the proposed algorithm is compared with that of a well-established benchmark scheme. The extensive simulation results demonstrate the effectiveness of our proposed algorithm.","PeriodicalId":125740,"journal":{"name":"IECON 2022 – 48th Annual Conference of the IEEE Industrial Electronics Society","volume":"306 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115874090","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}

Humans do not have an exact self-position, but rather, they recognize an approximate location based on surrounding information and envision the path to the goal to reach the destination. Therefore, this study examines a navigation method that plans a route based on an abstract map, such as a hand-drawn map, and then travels independently to the destination.","PeriodicalId":125740,"journal":{"name":"IECON 2022 – 48th Annual Conference of the IEEE Industrial Electronics Society","volume":"17 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131451377","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 proposed model uses a β-axis high frequency signal injection in order to model a new high frequency flux variable, which has similar properties to the standard electromotive force (EMF) used for high-speed sensorless control. Through the proposed model, the well established observer techniques from the literature can be used for rotor position and speed estimation. Thus, the low-speed sensorless scheme can be designed in similar form as the high-speed EMF based methods. Here, position and speed estimation are performed by an adaptive full-order observer, which is designed through a pole placement method and its stability constraints are investigated. Simulation results validate the proposed high frequency linear model and adaptive observer design method under sensorless vector control.","PeriodicalId":125740,"journal":{"name":"IECON 2022 – 48th Annual Conference of the IEEE Industrial Electronics Society","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132192591","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}

This paper investigates the possibility of achieving operation recognition by monitoring the human motion on a 2D map and classifying his/her path on the map, taken as an image data sample.
