Research Clearance Control of Servo Electric Cylinder Based on Linear Active Disturbance Rejection
In the face of the problem of reverse clearance in the loading process of servo electric cylinder,a solution of linear active disturbance rejection controller was proposed.a test platform for the fully closed-loop servo electric cylinder control system was built to complete the measurement of reverse clearance un-der the control of position loop PID controller;Taking the position loop of the servo electric cylinder control system as the control object,the linear active disturbance rejection controller is compared with the position loop PID controller through MATLAB/Simulink simulation and test analysis.The research shows that:Compared with PID controller,linear active disturbance rejection controller has short adjustment time,small overshoot and obvious reduction of dynamic tracking error under the action of step signal and sinusoidal signal.The performance of linear active disturbance rejection controller is better than PID controller,which can meet the demand of press assembly process.
