Despite its usefulness, there are no existing manuals or technical guides in dealing with DISs for net metering applications. Net metering refers to a system in which a distribution grid user has a two-way connection to the grid; this metering is appropriate for distributed generation as it charges or credits, depending on the user requirements, the difference between import and export energy.","PeriodicalId":202005,"journal":{"name":"2017 25th International Conference on Systems Engineering (ICSEng)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130600389","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}

Therefore, it is necessary to identify the occurrence of seizure in an epileptic patient and prevents patients from SUDEP (SUDDEN UNEXPLAINED DEATH IN EPILEPSY). Prediction of epileptic seizure through analysis of scalp EEG signal which is the measure of the brain's electrical activity avoid aggressive situation of epileptic patients during their seizure. This problem is challenging because the brain's electrical activity is composition of numerous classes with overlapping characteristics which vary significantly across patients. It is critical for separating seizure from other types of brain activity. In this proposed method, seizure detection process is implemented in FPGA using two main parameters of EEG signal such as frequency and amplitude which show variations during seizure. Input signal for this work was obtained from CHB-MIT database. The samples of input EEG signals were obtained in the form of .mat file for the duration of 10 seconds. This input file sample values of EEG signal are digitized which is in the form of sign magnitude representation for further processing in FPGA. Signals are used in text file format for Verilog programming. The first bit (MSB bit) represents sign of that particular sample. The frequency of the input signal was found using zero crossing counters. This count value was compared with general brain wave criteria. Similarly for amplitude level analysis, the remaining bits of input sample were compared with validation values. If there is any large deviation in any one of this comparisons found, then the signal abnormality can be predicted. After implementation, 82% of LUTs and 14% of registers were utilized. Timing summary for implementing this proposed work is obtained as 13.568ns.","PeriodicalId":202005,"journal":{"name":"2017 25th International Conference on Systems Engineering (ICSEng)","volume":"154 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131388726","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 controller is developed by transforming the space robot's equations of motion into the task-space. It is then assumed that the space robot's translational thruster forces are zero and that its manipulator has three or more degrees of freedom. This presents an over-determined system of equations relating the space robot's actuator torques to the net task-space forces and torques. A computed-torque inner-feedback loop is then developed utilizing the pseudo-inverse solution that minimizes the norm of the actuator torques. The kinematics of the space robot's end-effector are then stabilized about a commanded pose with an error-quaternion based attitude control and a proportional translational position control. The computed-torque control is then further designed so that it drives the space robot at the velocities that stabilize the kinematics. This control technique is simulated on a space robot possessing a six degree of freedom manipulator.","PeriodicalId":202005,"journal":{"name":"2017 25th International Conference on Systems Engineering (ICSEng)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123051586","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}

Manufacturing processes produce systems whose coefficients vary from the desired coefficients of the system designs. In [1], the authors presented a method for combining the measurements from several analog systems, that are nominally the same, using a technique based on the concept of dynamic element matching discussed in [2]. A heuristic analysis in [1] and a simulation in [3], indicated that this method can effectively control the output errors when the outputs of the several systems are corrupted due to manufacturing errors. In a recent paper [4], a rigorous analysis of a dynamic system matching technique (DSMT) applicable to a small class of scalar single input-single output (SISO) analog systems showed that for that class of systems the DSMT reduces the power in the output noise due to manufacturing errors. In this paper, those results are generalized to a class of linear SISO systems defined by general linear state space equations.","PeriodicalId":202005,"journal":{"name":"2017 25th International Conference on Systems Engineering (ICSEng)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114151469","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}

Designs and verifications of NoCs are based on either software simulations, which are extremely slow and inaccurate for complex models, or hardware emulations using low/mid-class FPGAs, where the scalability of the NoC system is intensively restricted by the limited on-chip resources. In this paper, we implement a parameterized NoC emulation system, capable of verifying complete functionality of routers and monitoring network performance and buffer usages in real time, on a hardware platform featuring a super large FPGA chip, Xilinx Virtex-7. This FPGA-based emulator also shall be configured to support multiple routing algorithms and packet transferring mechanisms. Compared to the existing emulators, it requires less user effort to measure the performance under various application scenarios, and it scales well to emulate large NoC designs. Currently, this emulator has been used to study NoCs with sizes of 4x4 and 8x8. For the case of 4x4 (8X8) NoC emulator, data transfers between routers can run at over 50MHz, and only occupies about 6% (25%) of the FPGA logic block resources.","PeriodicalId":202005,"journal":{"name":"2017 25th International Conference on Systems Engineering (ICSEng)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121202885","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 spacecraft model includes uncertain parameters as well as external disturbance torques. The modified Rodrigues parameters are used here to describe the orientation of the spacecraft. The objective is to control the three attitude angle trajectories to the origin, using control torquers, located on the central rigid body, despite uncertainties in the spacecraft dynamics. Based on the L1 adaptive control theory, a new attitude control law is derived. The control system includes a state predictor in the feedback loop to generated estimates of the unknown parameters and lumped unknown functions. The control signals are generated by passing estimated stabilizing control signals through a low-pass filter. The control law is synthesized using only the attitude angles and angular velocity of the spacecraft. Interestingly, the control law is independent of the elastic dynamics. In the closed-loop system, the attitude angles are controlled to the origin and flexible modes are stabilized as well. The designed control law achieves quantifiable performance bounds by the choice of large adaptation gains. Simulation results show that the L1 adaptive law accomplishes precise attitude control and vibration suppression, despite parameter uncertainties and external disturbance moments.","PeriodicalId":202005,"journal":{"name":"2017 25th International Conference on Systems Engineering (ICSEng)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125803073","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}
