Extended state observer based repetitive control and applications

Many examples in nature show periodic characteristics ranging from the orbital motion of the universe to the rhythm of the heart. There are various instances where the mathematical model of the plant is not available and most of the controller design is dependent on the plant parameters. The novel algorithm proposed in this thesis, will be able to design the controller without the plant model. Moreover, it will eliminate any type of input and output disturbances from the system. As a result, the system will be efficient and disturbance free.
