Abstract

Control method FOC - IM is a control method used very popular today. With
the principle of creating a tool that allows recognition of squirrel cage induction
motor has the same physical nature as separately excited DC motor. With the FOC
- IM power transmission system, the power circuit is often selected as a multilevel inverter, with the method of modulating the space vector. However, with
the multi-level inverter structure when you want to use for the transmission
system at a higher capacity (higher level), the construction of space vector is
difficult, takes a lot of time (large calculation volume). This paper will propose
the method of generalizing the FOC - IM transmission system by generalizing the
method of spatial vector modulation of multilevel inverter. From there, the FOC -
IM drive system can be applied to the desired power (desired number of levels).
The model results on Matlab - Simulink of the proposed method with pump and
blower loads have proven the effectiveness of the proposed control method
