Abstract :
This paper describes realization of a fast current control system of permanent magnet synchronous motor (PMSM) based on model predictive control (MPC). This current controller directly selects one of the switching modes of a PWM inverter, while conventional one generates voltage reference regarding an inverter as ideal amplifier. The problem with selecting the switching mode to output is formulated based on MPC. By considering an inverter specifically, we can use not only a sinusoidal PWM mode but also an overmodulation mode without special handing. And in this paper, real-time implementation method using a look-up table, which is designed beforehand, is discussed and the experimental results are shown.
