Description
technical field [0001] The invention relates to the technical field of control, in particular to a semi-physical simulation system for traction control. Background technique [0002] Simulation technology integrates a variety of modern cutting-edge means in contemporary science and technology, greatly expands human vision, time limit and ability, and plays an extremely important role in the field of science and technology. From a certain point of view, the development level of a country's simulation technology also represents its overall scientific and technological strength. [0003] In the prior art, the traction control simulation software is a simulation program developed based on a PC software platform (such as MATLAB, Simplorer, SABER, or C / C++, etc.), that is, a pure digital simulation. [0004] However, the existing technology has the following defects: since modern AC drive systems all use digital traction controllers, the dynamic and steady-state performance of mo...
