An automatic modeling method for a user-defined vehicle controller includes: configuring a component model; generating a description file; summarizing component input and output signals/parameters; and creating the user-defined vehicle controller. A template and data required by the user is provided to automatically build a vehicle controller port model, and a vehicle controller policy model framework to assist the user to quickly and flexibly build the vehicle controller model is provided. The problem of low efficiency in building various user-defined vehicle controller models for different vehicle types is solved. The user develops a vehicle controller policy model under the given model framework, and the model can run directly without additional configuration of port signals. The user can modify the vehicle controller policy model online in real time, which solves the problem that the application configuration of the vehicle controller is complex and cannot be updated online in real time.

The present invention relates to a direct torque control method for inhibiting torque ripples, mainly comprising the following steps: establishing an MC voltage vector switching table visually displaying degrees of change in torque and flux, and, proposing, on the basis of the MC voltage vector switching table visually displaying the degrees of change in torque and flux, an MC-DTC mark-to-space ratio computing policy for torque quantification control. The MC-DTC mark-to-space ratio computing policy allows for inhibition of torque ripples of a PMSM speed control system and for a constant switching frequency, uses the MC voltage vector switching table visually displaying the degrees of change in torque and flux, has a simple algorithm, does not reply on motor parameters, and obviates the need for rotational coordinate transformation.
