SYSTEME DE CONTROLE D'UN ONDULEUR DE TENSION

摘要

A voltage inverter (1) supplies an asynchronous motor (MAS) and an estimating module (3) uses motor current and inverter continuous voltage signals (E) to generate estimates of stator flux and motor torque. These data are supplied to comparators (61,62) and flux sector calculator (63) to provide error signals and flux position to direction and control tables (81,82) which produce first and second control vectors during sampling period
