—To keep phase balance and improve output voltage quality, a novel multiple-loop control system in 400-Hz inverter power supply based on unipolar sinusoidal pulse width modulation (SPWM) is proposed. The causes of phase imbalance in a three-phase combined inverter power system are analyzed, and a new multiple-loop control strategy based on phase control is(More)
In order to resolve the pouring state recognition problem of continuous casting slag detection system (CC-SDS) and reduce its control delay, a kind of C language integrated production system (CLIPS) based CC slag detection expert system (SDES) was brought forward. Multi-channel real-time vibration signal collection system oriented to slag detection was(More)
