“…This needs to be optimized and selected in combination with the actual situation of colleges, so as to obtain the extensible strategy with better results, that is, to perform an extension performance analysis of college mental health education. There are many performance analysis methods [20][21][22][23], but considering that performance analysis indicators may have ambiguous positional relationships, this paper chooses the extension correlation function [24][25] for analysis.…”

Currently, mental health education in college is constrained by various factors (e.g. the complex mentality of college students). This paper mainly discusses the extensible strategies for mental health education of college students, and develops a performative analysis model of these extensible strategies. Firstly, the problems in mental health education of college students were enumerated, and an extension model was set up for mental health education in colleges. On this basis, the extensible strategies were generated for college mental health education. Then, a performance analysis model was presented to effectively select and optimize the extensible strategies. The research results provide a theoretical guide for solving complex problems with extension strategy and promoting mental health education in colleges.

“…If one of the transistors of the inverter is in opening defect while the control of the complementary transistor is active, the short circuit of the DC power supply is inevitable and to avoid this kind of inconvenience, it is imperative to act either by canceling the control of the other transistor, or by using a fuse protection whose fusion is ultra-fast [6,7,13,15].…”

Previously, a particular interest is focused on embedded systems and isolated sites, given that troubleshooting is not obvious in the short time. Currently, after the onset of the COVID 19 pandemic and due to the confinement imposed on almost all the countries of the world, immediate or timely repair may be impossible. Reason why, this document provides for the study of the behavior of a pumping system, having to fill a water tower with a capacity of 150 m 3 with a TDH of 17 m, during the loss of a phase, two phases or even three phases of feeding, in order to ensure control of the process and guarantee continuity of service, especially in these periods when hygiene and cleanliness are required to minimize the risk of contamination. The results obtained show that the DSIM can still rotate even in the event of loss of supply phases or short circuit in the stator windings and provide the torque necessary to pump water under degraded conditions and after this analysis, it turns out that thanks to its flexibility and its operation in degraded mode, the DSIM will be widely used. The global system is dimensioned and simulated under Matlab/Simulink Package.

“…There is therefore an orthogonal basis of eigenvectors in which the magnetic quantities of the motor are decoupled. This certainly makes it easier to control the induction motor [15][16][17][18]. Using the transformation Eq.…”

An improved dynamic behavior of water pumping system is presented in this paper. The system consists of a seven-phase induction motor powered by a photovoltaic generator (PVG) and a battery bank, via two static converters controlled independently. A boost converter based on fuzzy logic controller is utilized to adapt the voltage of the photovoltaic generator in order to extract maximum power. A three levels neutral point clamped inverter (NPC) is introduced to attain a low voltage harmonic distortion in the system. In addition, an improved direct field oriented control with minimizing non-sequential currents for the seven-phase induction motor using fuzzy logic filter is implemented. To verify and validate the proposed system, an optimal operating point is chosen to locate the dynamic and static operating limits of the system. Moreover, the proposed system is simulated and analyzed. The minimization of the non-sequential currents component induces a quality energy improvement with minimizing of the Joule losses, which increase the system efficiency. The use of the seven-phase machine brings a degree of additional freedom to the system, its tolerance to faults is a capital issue for the isolated places.
