Abstract EN
The lever-type electric erection system is a novel kind of erection system and the experimental platform in this paper operates with varying loads and low-resolution encoder.
For high accuracy trajectory tracking, linear active disturbance rejection control (LADRC) is introduced.
An approximate model, consisting of the servo system configured at velocity control mode and the lever-type erection mechanism, is built by means of system identification and curve fitting.
Reduced-order LADRC based on the further simplified model is proposed to improve tracking accuracy and robustness.
As comparisons, traditional LADRC and PID with high-gain tracking differentiator (HGTD) are designed.
Simulation and experimental results indicate that reduced-order LADRC can realize higher trajectory tracking accuracy with low-resolution encoder and has better robustness to variation in erection loads, compared with traditional LADRC and PID with HGTD.
