Modeling Design of Controller of Frequency Converter of Electric Traction Shearer Based on UML

Aiming at the design defect in traditional design of electric control system of mine-used electric traction shearer, the paper proposed a scheme of requirement analysis and design of system based on UML modeling method in the early days. It introduced the modeling design method based on UML with example of modeling design of controller of frequency converter of electric control system of mine-used electric traction shearer.
