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. Keywords: FOC, Multi-level H-bridge inverters, space vector modulation. |
