Description

Technical field: [0001] 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. Background technique: [0002] 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 addition, due to the conti...
