摘要

This paper presents a developed switched reluctance linear launcher system with the three-phase 6/7 structure single side switched reluctance linear launcher, the three-phase asymmetric bridge power converter and the semi-physical emulator RT-LAB digital controller in hardware and software flow diagram. The velocity-acceleration double closed-loop control of the mover is proposed and verified for the first time. The internal loop is acceleration loop and the external loop is velocity loop. The turn-on angle and the turn-off angle of the main switches in the power converter are fixed. The velocity difference is the input of Regulator 1 whose output is the expected acceleration value of the acceleration loop, the difference between the expected acceleration value and the practical acceleration value is the input of Regulator 2 whose output is phase current chopping limitation. The expected acceleration is made certain by the velocity difference, and the phase current chopping limitation is made certain by the acceleration difference. The developed prototype is tested experimentally. It is shown that the velocity response of the mover in the system is smooth, and there is no velocity overshoot with fast velocity arising by adopted Fuzzy-PI control algorithm.
