Observer Implementation in an FPGA Using Simulink and Xilinx System Generator

Abstract: In order to reduce the cost of the current switched resonant power converters, a state observer is introduced to provide the controller with the required information for the effective switching of the converter without the need of expensive sensory inputs from the resonant circuit. This Master's thesis investigates the usage of Matlab/Simulink and Xilinx System Generator as an implementation tool for Field Programmable Gate Array (FPGA) development of the Observer Model. The main aim is to keep the model size to a minimum while keeping the error within a reasonable range, allowing the observer to converge.
