Observer Design Using Luenberger’s Observer

Authors : Yongho Jeon and Shinwon Lee

Abstract: Commonly used solenoid valves are mainly used for industrial equipment and appliances where simple ON/OFF operation is possible. This is because the structure of the solenoid valve is simple and the production cost is low. It is possible to simply use the alternating method of applying the drive rated voltage or turning off the power. This study designs a controller for precise position control and a Luenberger’s observer for unobserved states in the use of solenoids commonly used in the industrial field. In designing an observer an observer with a disturbance state including a non-linear term and a constant load is designed and an appropriate gain is set. As a result, the position error was within 0.1% within about 0.1 sec of the steady state, the state estimation for the disturbance could be possible and it could be used in the position controller.
