Abstract

The invention relates to the technical field of electric control systems of electric-wheel trucks, in particular to a method for simulating an electric drive control system under a traction working condition of an electric-wheel truck. Under the traction working condition, the control system consists of a main generator constant power control part and a wheel motor excitation control part, whereinthe main generator constant power control part designs and simulates a main generator excitation current link, decides time constants of various control links and selects a structure of a current regulator, calculates parameters so as to obtain a simulation map, and analyzes the structure of a main generator to obtain a simulation map; the wheel motor excitation control part designs and simulatesa wheel motor excitation current link, decides time constants of various control links, selects the structure of the current regulator and calculates parameters so as to obtain a simulation map; thetwo parts are combined, and the dynamic structure of a wheel motor is considered, so a simulation structural drawing of the whole control system under the traction working condition is obtained; and acontrol strategy for a constant power link in the simulation structural drawing can adopt the classical PI control or fuzzy control.

Description

technical field [0001] The invention relates to the technical field of electronic control systems for electric-wheeled vehicles, in particular to a simulation method for the electric transmission control system of electric-wheeled vehicles under traction conditions. Background technique [0002] Electric wheel vehicles are ideal and efficient transportation equipment in large-scale open-pit mines at home and abroad, and play an extremely important role. Its electric transmission adopts the STATEXIII type control system of GE Company of the United States. This system can control the car in real time, and through the online dialogue of the notebook computer, the relevant running data of the car can be obtained. At present, computer simulation technology is more and more widely used in automatic control, but for the system modeling and simulation of electric wheel vehicles, such research has not been published. [0003] However, it does not reveal the control structure of the ...
