Abstract


The stator current control loop plays an important role in ensuring the quality of electric drives. When the current controller provides ideal responses, speed control design subsequently is in charge of improving the system performances. PID control is commonly used current loop design, this paper presents the comparative analysis of current stator controller using proportional integral control and predictive current control (PCC) in field-oriented control based induction motor drives, with rigidly coupled loads. The experimental results show system responses with PID and PCC. The research results provide primary guidance in selection between the two controls.
