The aim of this project is to use variable prediction horizon nonlinear model predictive control to achieve near perfect harmonic suppression for inverters in the face of realistic and unavoidable switching delays. Other aims include further performance improvement based on the application of Kalman observer, and extension of the ideas to a variety of switching topologies and validation of the results by simulation and experiments. The intended main outcome of the project is the development of a methodology for non-interfering operation of inverters, particularly, in grid connected applications. This is expected to facilitate a further integration of renewable energy and highly efficient power utilisation. Both factors are crucial in the sustainable clean energy future.Read moreRead less
