Anti-disturbance Pseudo Derivative Feedback Strategy for Motor Control Based on a Load Observer
摘要
Abstract
To further improve the anti-load disturbance ability of motor control based on pseudo derivative feedback (PDF)strategy,we embed a reduced-order load torque observer into a PDF strategy control system.Using the measured rotor angle as the known parameter,a reduced-order load torque observer is designed.A control law,governing the embedding of the reduced-order load torque observer into the PDF strategy motor system, is deduced.It results in the development of an anti-disturbance PDF strategy motor control system with better anti-load disturbance ability.In order to verify the anti-load disturbance ability of the new PDF strategy motor control system,a practical case study is used to establish the simulation model.The simulation results reveal that the PDF strategy motor control system with a reduced-order load torque observer has a better anti-load dis-turbance ability than an ordinary PDF strategy motor control system.关键词
