摘要
Abstract
To further enhance the control accuracy of rotor systems,a semi-closed-loop control system for a servo electric cylinder integrated with a synchronous belt reducer is designed,based on the Linear Active Disturb-ance Rejection Control(LADRC)theory.The mathematical model of servo motor and the dynamic model of elec-tric cylinder,incorporating the synchronous belt transmission,are established,and a complete simulation platform is subsequently constructed in the MATLAB/Simulink environment.Numerical simulations are conducted to system-atically investigate the effects of the synchronous belt preload and the axial load of the electric cylinder on the mo-tion behavior of the swashplate.The simulation results reveal that during collective pitch control of the rotor,the swashplate produces an additional tilt angle,the magnitude of which is closely correlated with the synchronous belt preload and the axial load,thereby elucidating the influence mechanism of the flexible transmission components on the control accuracy of the rotor blade pitch angle.关键词
