Abstract
First, a certain type of ship azimuth servo system as an example, mathematical model with friction is established, then using LADRC to estimate and compensate the friction disturbance, greatly inhibit the effects of these disturbances on the servo system. The simulation results show that the method of ADRC can greatly improves system capacity and anti-friction disturbance.
