Although many aspects of repetitive controller design have been introduced in this thesis for power electronics applications, there are still a lot of possibilities for technology improvement:

• The power converter modeling still suffers from uncertainty disturbance, which influences the repetitive control parameter setting. In practice, some of the parameters are tuning using the method of trial and error. Detailed research should also be done on the power converter modeling and circuit uncertainty estimation.

Lagrange interpolation method, and this method is simple to implement but a little sensitive to the noise. In the future, many other polynomial interpolation methods should be compared on the VVS and fractional-order RC scheme.

• The ideas of repetitive control and iterative control have only limited applications on repeated conducts or iterative actions. It is because that the repeated or iterative learning is supposed to only base on physical repeated experimental results. The application requirements of repetitive or iterative control have restricted their method applications. However, for a non-periodic reference signal process, the simulation process can be done many times identically. After multiple simulations based on the same reference signal, the control performance can also be improved by using the iterative learning method. Therefore, the repetitive or iterative control method can expend to the model-based algorithm and be applied to more and more implementations, e.g. autonomous vehicle and robotics area.
