一种数字阀控制摆动缸高精角度系统设计和仿真
Design and Simulation of Digital Valve Control Rotary Actuator System with High Angle Precision
摘要
Abstract
To meet the requirement of actuator servo positioning precision outdoing 0.01°,a system solution of rotary actuator servo controlled by step motor is proposed.Its system schematic daigram is set up based on objective request.The rotary actuator mathematics model controlled by digital valve and dynamic transfer function is built as designed by requirement,the Bode plot analysis and step signal dynamic simulation are carried out,and a new method making use of allowable stable gear ratio for precision assurance is proposed to determine the basic digital valve parameters and rotary actuator parameters.The proposed system solution of the digital valve control rotary actuator can achieve highly precise angle control of high torque,with wide application in the future.关键词
