Model Reference Adaptive Modeling Method of Ball Screw Feed System

Abstract:

A model reference adaptive modeling method of ball screw feed system is proposed. Using a low-level system with excellent dynamic characteristics as the reference model and ball screw feed system as the controlled object, this paper establishes model reference adaptive system by Narendra program, achieving exact match between the adjustable system and the reference model through experiment and deriving the low-level model of the ball screw feed system. Then taking the X axis of X-Y work table as an example, a second-order model of the ball screw feed system is established by this method. When 40000 pulse signals are input into the model and the ball screw feed system in 160s respectively, the output error between the two is within ± 0.005mm, thus testifying the higher accuracy of the model obtained.
