However, this method like other control methods has some disadvantages which one of them is the need to parameters detuning of LIM. On the other hand, parameters of the LIM are changed by changing condition like changing temperature. So, if the motor parameters are not been calculated accurate, the control of speed and THD of the current may become worse. In this paper, an improved MPC is proposed to solve this problem. The proposed Structure is resistant to changes in the parameters of the LIM. The proposed structure uses an ultra-local model instead of mathematical model of the LIM. Also, in the proposed structure, for estimate of disturbance and improve the control of speed, a Linear Extended State Observer (LESO) is used. According to the results, Proposed Structure have less ripple of speed’s path than Field Oriented Control (FOC), Conventional Direct Thrust Force Control (DTFC), DTFC-PI, Deadbeat-based Predictive Current Control (DPCC) and Conventional MPC. Also its ripple of the output speed is less than Conventional DTFC, DTFC-PI, DPCC and Conventional MPC. One of the other advantages of the proposed structure is fast speed of respond. In other word, in the proposed structure, actual speed achieves faster than FOC, Conventional DTFC, DTFC-PI, DPCC and Conventional MPC to the reference speed.","PeriodicalId":213924,"journal":{"name":"2022 13th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121012636","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}

However, with the increasing in the number of voltage vectors (real or virtual), the computation burden and complexity will be increased. Therefore, in this paper, a procedure to select the best triangular section that involves of the reference voltage vector and also reducing the number of candidate voltage vectors for placing in the voltage based cost function is presented.

Flying Capacitor (FC) multilevel inverter is an efficient structure that does not need different dc sources and is therefore suitable for electric vehicle applications. Moreover, Model Predictive Control (MPC) is a well-known control strategy for different electric drive systems like induction machines. However, MPC of electrical machines supplied with a multilevel FC inverter has not been investigated yet.As a result, this paper concentrates on the predictive control of an IM drive with 4-level FC inverters. The application of this control strategy is simple and many objective functions can be simultaneously taken into account in the optimization of the cost function, such as the dynamic tracking behavior and the voltage balancing of the FCs. To compensate the delay time which emerges due to a large number of calculations in each sampling instant, delay compensation method has been utilized. According to the results, the proposed predictive control of the IM drive with a 4-level FC inverter offers fast dynamic behavior with no overshoot, low torque and current ripples, and perfect voltage balancing of the FCs.","PeriodicalId":213924,"journal":{"name":"2022 13th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130523808","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}

Nevertheless, the conventional control methods of voltage source converters (VSCs), cannot work well under weak grid conditions. Direct power control (DPC) due to the simplicity of its system structure, the elimination of current controllers, and modulation blocks has attracted widespread attention. Some researchers have enhanced the control method by reducing the effects of unbalance under stiff grid conditions. Nevertheless, the weak grid conditions lead to voltage fluctuations at the point of common coupling (PCC) and consequently cause converter instability. This research proposes a sensorless virtual flux DPC of VSCs enjoys a stable performance under the unbalanced weak grid conditions using the proposed active and reactive power references. The proposed control system provides features such as high-power quality and better current THD in comparison with the conventional direct power control method. Also, the voltage sensors have been eliminated. The stability of proposed control system is provided using a small-signal model, where the model is directly extracted from a conventional switching look-up table. The stability analysis shows that it is possible to simultaneously change system parameters. These findings are verified through extensive simulation.","PeriodicalId":213924,"journal":{"name":"2022 13th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125625701","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}

A lot of insulated gate bipolar transistor (IGBT) switches in the converter considerably increase the probability of switch failure. In this paper, a fast and accurate approach is suggested to identify the open-circuit (OC) failure of IGBT switches in a four-level T-NNPC multilevel inverter. Using the suggested approach, the occurrence and exact place of OC fault are determined in less than one cycle. In the presented fault detection algorithm, the output current and voltage are exploited as detection parameters, in which the predicted and desired values of output waveforms are compared to the actual values. Then, the dissimilarity between the observed and expected values is utilized to find the exactly failed IGBT switch. The four-level T-NNPC multilevel inverter is simulated in MATLAB/Simulink environment, and the feasibility of the suggested method is demonstrated for OC fault conditions. In this regard, the effects of OC faults of switches on the capacitor voltages and output waveforms are investigated. The result of applying the suggested method is shown for all the switches separately.","PeriodicalId":213924,"journal":{"name":"2022 13th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC)","volume":"25 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124318985","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}
