Abstract

An FCS-MPDTC control system for a PMSM capable of expanding a voltage space vector output includes a proportional-integral (PI) controller, model prediction, vector adjustment, voltage observation, ABC-[alpha][beta] conversion, one-beat lag compensation, pseudo output voltage space vector selection, a two-level voltage source inverter and a permanent magnet synchronous motor. The control method, based on a torque control strategy capable of expanding an output voltage space vector range performed by two-step model prediction, can be developed on a comprehensive experimental platform of dSPACEand Typhoon HIL Q402. The system achieves good magnetic flux linkage and torque control performance, a small amount of calculation related to the algorithm, low current total harmonic distortion (THD), low development cost of the hardware requirements, and fast and real-time result monitoring, and is universal in development and test of power electronic drive systems.

Description

[0001] (1) Technical field: [0002] The present invention relates to the relevant technical field of motor control, especially a PMSM (Permanent Magnet Synchronous Motor, permanent magnet synchronous motor) FCS-MPDTC (Finite-Control-Set Model Predictive Directive Torque Control Strategy, finite control set model predictive direct torque control strategy; it has the characteristics of expanding voltage space vector output; Voltage Space Vector, referred to as VSV, voltage space vector) control system and method. [0003] (two) background technology: [0004] The non-renewability of fossil energy and the deteriorating human living environment are gradually placing new demands on traditional travel methods. In the road-based travel mode, new energy vehicles can effectively reduce or eliminate their own pollutant emissions, which is conducive to efficient use of energy, centralized treatment of pollution and improvement of the quality of the main living environment. subject. In ...
