Optimal LCL-filter Design Method with Model Predictive Control (MPC)
In this project, you will compare conventional LCL-filter design methods and analyze the impact of controllers on the design methods. Then, you will investigate a new design method of LCL filters when MPC is applied.
Keywords: Model Predictive control, MPC, LCL-filter, design method
At HPE, model predictive control (MPC) is investigated as an alternative
control method for power electronic systems (PES). MPC is a very suitable
solution for grid-connected converters with LCL-filters because MPC can
stabilise the system without any limitations on system parameters despite
possible resonances. Therefore, conventional design limitations on the
filter parameters can be relieved, and LCL-filter design methods can be
improved.
In this project, you will review conventional LCL-filter design methods and
analyze implementation approaches for inductors. Then, you will investigate
the impact of the relieved design limitations for the case when MPC
is applied. Furthermore, the influence of other variables (e.g. power-level,
switching frequency, and core/winding types) should be fully considered to
have a comprehensive investigation of the impact on the design method.
