The nonlinear biological process transformed to a fuzzy Takagi-Sugeno (T-S) model, then a nominal control based on the optimal Linear Quadratic Integral (LQI) is synthesized for ensuring the trajectory tracking. To build the active fault tolerant control, a Proportional Integral Observer (PIO) is proposed to estimate simultaneously the actuators faults and states, the estimated faults used to reconfigure the nominal control. the new conditions of convergence to increase the fault compensation speed are proposed, which based on multiple Lyapunov functions.

This work is a first step towards an IoT solution, appropriate for small power, but spread renewable energy solutions as in smart residences. The OPC protocol is chosen as the most suitable solution for long distance communication, whereas serial communication is employed for short distances. The OPC server/client platform is microprocessor based, while the generators are controlled through microcontrollers that interact through serial communication with local OPC nodes. The microcontrollers can provide the supervisor with different parameters, such as voltage, current, control value, but can also receive parameters, such as the set point of the generated power, solar irradiation, temperature. The multiplatform capabilities of the python language are considered. A validation is realized via Arduino boards as local controllers for the generators and Raspberry Pi boards as OPC server/clients and a global supervisor is developed in Matlab. The solution is interesting as it gives a strong modularity and easy access to portable solutions on the ground.","PeriodicalId":153985,"journal":{"name":"2018 7th International Conference on Systems and Control (ICSC)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123197918","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}

Simulation studies are presented while considering in the first step, the nominal parameters of the system, and in the second step, variations or uncertainties that can impact the inductance of the RL filter.

Considering sensor noise and disturbance, an unknown input observer (UIO) is developed. In this scheme, by building an augmented system with a filter, sensor fault and noise of the original system become into a part of actuator fault and disturbance. According to this augmented system, an UIO and fault estimation method have been designed. Then, by solving the linear matrix equalities (LMEs) and the linear matrix inequalities (LMIs), the parameters of the UIO are obtained. In addition, we analyze the convergence of the observer. In order to verify the proposed method, a wind turbine system with torque actuator fault and pitch angle sensor fault has been tested.

The proposed algorithm can track the real GMPP under any PSC patterns and under any weather conditions with improving the tracking speed and reducing the PV output power oscillations at the steady state. The proposed algorithm is simple and easy to implement, because additional sensors or electrical switches are not required to identify the GMPP. The idea of the proposed method is based mainly on the scanning of the PV curve with a variable step of the duty cycle from zero to one. The scan step will be small when the operating point is near the MPP, otherwise, the scan step will be large to skip the regions that do not need to be scanned on the PV curve. Therefore, the scan time will be reduced and the MPPs are accurately detected. Furthermore, the algorithm stores only one MPP during the scanning process, stores only the data position of the greatest maximum power of the PV curve in each sample time Ts. Therefore, the execution of the embedded program in the calculator is optimized. In order to maintain the operating point at the GMPP after the scanning is finished a simple proposed sub-program will be used. In this work, a controlled Cuk DC–DC converter was used and connected to a Kyocera KC50T PV panel to verify the performance of the proposed method. Matlab/Simulink™ was used for the simulation studies.","PeriodicalId":153985,"journal":{"name":"2018 7th International Conference on Systems and Control (ICSC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133379467","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}

Whereas well established control techniques like optimal LQG or PID controllers may perform well under assumption of the linear structural behavior, which can be described with sufficient accuracy by an LTI model, control task becomes much more complex in the presence of nonlinearities and uncertainties. In this paper we propose a feedback controller based on the recurrent wavelet neural network (RWNN) which is designed and trained to track the states of an ideal state-feedback controller, designed for the underlying linear model of the plant. In addition, adaptive neural network observer is designed to estimate the unnknown model dynamics associated with the nominal LTI model of the plant. Real time implementation of the proposed controller is realized on a Hardware-in-the-Loop setup with a flexible clamped-free beam and dSPACE system and tested for disturbance rejection tasks through a worst-case study in the presence of disturbances which cause resonant states.","PeriodicalId":153985,"journal":{"name":"2018 7th International Conference on Systems and Control (ICSC)","volume":"521 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130177356","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 presented result is in the form of BMI (Bilinear Matrix Inequality) which is transformed into LMI (Linear Matrix Inequality) through an interesting approach. The resulting constraint can be easily achieved with standard software algorithms.
