Mechanical Decoupling Algorithm Applied to Electric Drive Test Bed

Abstract EN

New approach and analysis are proposed in this paper to enhance the steady and rapidity of the electric drive test bed.

Based on a basic drive motor dynamometer system (DMDS) test bed, detailed mathematical model and process control are established and analyzed.

Relative gain array (RGA) method and diagonal matrix method are used to analyze the mechanical coupling caused by mechanical connection on the DMDS test bed, and the structure and algorithm of dynamic decoupling are proposed.

Simulation and experiment all indicate that the designed decoupling method can efficiently improve the control accuracy and response speed.
