Modeling and Analysis of Harmonic in the Mine Hoist Cnverter Based on Double Closed-Loop Control

In the process of converter driving mine hoist, the output voltage waveform of the inverter is distorted. A novel feedback control method based on the filter inductor current inside loop and voltage is developed in this study. The transfer function model of the two closed-loop control is builded. Parameters of the PID controller are determined through theoretical calculation after analysis of t...
