This method, based on the concept of fast terminal sliding mode, aims to ensure the finite-time convergence of the system states as fast as possible without singularity problems. Moreover, the effects of disturbances and uncertainties are overcome while avoiding the chatter problem thanks to the improved adaptive law. Using the Lyapunov theory, the semi-globally fixed-time stability of the whole closed-loop system is proved. Numerical simulations are carried out as an illustration of the efficiency of the proposed method.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122263285","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 this output-feedback control scheme, to accurately and quickly construct the unmeasured states, a robust high-gain observer is constructed. The latter, which is characterized by a unified design function for the correction term, represents a large class of linear or nonlinear observers such as high-gain observers, (non-smooth or smooth) sliding mode observers. To overcome uncertainties in the system’ mathematical model, an adaptive fuzzy logic-based control approach is employed. Unknown fuzzy parameters are robustly updated via a new proportional-integral law improved by a σ -modification term. The corresponding stability analysis is performed via a Lyapunov type method.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116323401","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 strategy allows to adapt the configuration of the quadrotor when severe fault is occurred in one rotor. The reconfigurable quadcopter changes its shape by folding the two adjacent rotor arms to the damaged one and performs as a trirotor. Since the shape transformation induces a variation of vehicle's center of gravity which results variations of the inertia and the control matrix, an emergency sliding mode controller is designed based on control allocation matrix, where the control efforts are redistributed among healthy actuators in the resulting configuration of the quadrotor. Simulation results show that the proposed strategy is successful in controlling the damaged quadrotor until achieving its trajectory.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126428342","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}

These three subsystems are connected to electrical grid through dc-ac converter. Fuel cell-based systems allow avoiding the intermittence and discontinuous character of several renewable energy resources, such as photovoltaic energy and wind energy. The main drawback of fuel cell stack is its slow dynamics. To overcome this drawback, supercapacitor is used to supply or absorb the power during transient and fault conditions. A model predictive controller is designed in order to achieve the following purposes: extracting maximum power from the fuel cell stack, regulating the dc bus voltage and controlling the active and reactive power of the grid.

Chaotic systems exhibit interesting features for image cryptography, and their hardware implementation is a challenging task to accelerate the cryptosystem. This paper proposes an FPGA implementation of a robust Fixed-Point Cubic-Tent Map Pseudorandom Bit Generator (FPCTM-PRBG) image cryptosystem for a real-time application based on the Xilinx System Generator (XSG). We designed the new FPCTM-PRBG using XSG to produce the keystream sequence. Then, the encryption is performed using the XOR operation between the plain image and the FPCTM-PRBG stream sequence to get the cipher image. The decryption process is executed by XORing the encrypted image sequence with the FPCTM-PRBG. The algorithm is designed, implemented, and validated using Vivado/System Generator tool through the FPGA-ZC702 evaluation board. The performance of the proposed cryptosystem is evaluated based on statistical analysis, differential analysis, PSNR, and image entropy. Also, hardware co-simulation is performed to test the image encryption system in real-time using a generated JTAG co-simulation system. Thus, the architecture of the proposed cryptosystem is flexible due to the FPGA design. The obtained results prove the higher performance and high-security level of the proposed cryptosystem with low power consumption (238 mW) and a reduced encryption time.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130386879","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}
