The tracking of a given voltage in the traditional double closed-loop proportional integral control current power grid simulator has problems such as static difference, delay and oscillation. It is proposed that outer loop inner inverter side adopt quasi-proportional resonance respectively, topology adopts cascaded modular design to establish single-phase model. Compared with proportional-integ...

Abstract In this research paper, we improve some fractional integral inequalities of Minkowski-type. Precisely, use a proportional operator with respect to another strictly increasing continuous function ? . The functions used in work are bounded by two positive get reverse Minkowski new sense. Moreover, introduce which have close relationship the Minkowski-type via -proportional integral, then...

Abstract Magnetic levitation is a phenomenon of objects by using magnetic field to defy gravity. an interesting research topic widely used in industry or transportation such as trains, conveyors, lifts, and many more. In general, can be realized regulating the current source. However, due normally unstable power supply source, results instability. Therefore, control system needed stabilize syst...
