One of the network types is mesh network where space division multiplexing (SDM) has become an interesting approach to deal with the upcoming capacity crisis issue. SDM's key concept is to take advantage of the spatial dimension to significantly increase transmission system power. In this paper, we present an adaptive cost shortest path based heuristic for flexgrid SDM optical networks. The preliminary experimental results show a promising performance in terms of minimizing the highest used number of slices over all the links/cores of the network.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"141 1","pages":"132-137"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73269359","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}

Electricity generation from wind energy has significant contribution in renewable energy applications inside microgrids. However, decupling between wind generator and microgrid, due to presence of grid interface converters (GIC) for integration and maximum power point (MPP) operation, reduces the microgrid inertia compared to traditional generation system. This inertia reduction has adverse effect on the frequency stability, nadir, and rate of change of frequency (ROCOF), when the microgrid is experienced to load or generation disturbances. A lot of efforts have been made through generators deloading techniques and/or using of energy storage systems (ESSs) to introduce synthetic inertia in the system. The aforementioned techniques have financial drawbacks. Utilizing the natural inertia of wind generation system to enhance the microgrid inertia still requires additional efforts. In this article, the inherent inertia of the wind generation system, the fast control capability of GIC, and advancement in control technique are employed to introduce inertia response into the microgrid, while the wind generation system works very near to the MPP. In addition, the applied control technique uses the frequency signal instead of the frequency derivative, which avoids deterioration of the system stability and averts noise amplifications. The controller is tuned to mimic the inertia performance of traditional generation. The mathematical derivation which necessary for the control objective is deduced and verified by simulation using MATLAB platform. The technique is applied on microgrid comprises of wind generation system, thermal generation unit and electrical load. The response of the microgrid with suggested control is justified with the performance of two other microgrids operate under the same disturbance.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"39 1","pages":"155-160"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85036977","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}

Such walker robot is a 2-DOF biped that descends an inclined surface without any actuators. Its bipedal walking is modeled by a complex system, which is characterized by a nonlinear dynamics with impulse effects. We show the complexity of the bipedal walk by analyzing the bifurcation diagrams which reveal the existence of undesirable phenomena such as different bifurcation types and chaos. In order to properly imitate human locomotion, the chaotic bipedal walking of the compass robots walkers should be transformed into a one-periodic stable behavior. Hence, to achieve this goal, we propose an improved PD+ control law, which is based on the PD controller and the gravity compensation. Finally, and via some simulations, we demonstrate that the bipedal walking is controlled and hence chaos is suppressed.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"28 1","pages":"482-488"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81180366","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 control strategy proposed in this work aims at stabilizing the closed loop system, although sensor faults exist, as well as compensating their effects. For this, a multiobserver is designed so as to estimate, at the same time, the system states and the sensor faults. For the design of the sensor fault-tolerant fuzzy T-S controller, we base the analysis and the stability study on the Lyapunov quadratic function and the Linear Matrix Inequalities (LMIs) formulation. Furthermore, the performance optimization technique aims to reduce the derivation impacts of sensor faults on the system states and estimation errors. The multiobserver and the fuzzy T-S controller gains are simultaneously determined by the resolution of the LMI conditions. Finally, the control approach proposed in this work is applied in simulation to a real example which is a manipulator arm operated by a DC motor, so as to show the suggested control technique efficiency.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"28 1","pages":"239-244"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78312708","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}
