FIL Simulation of Sliding Mode Controller for DC/DC Boost Converter

This paper discusses real-time FPGA implementation of a nonlinear robust control technique namely Sliding Mode Control (SMC) for a DC/DC boost converter. Mathematical model of the DC/DC boost converter is first described and Sliding Mode Control law is designed for the plant model. The controller is then implemented in FPGA device using Xilinx System Generator and FIL (FPGA-IN-THE-LOOP) simulations are performed to test robustness of the system and its sensitivity to load and input voltage variations in Simulink environment using Xilinx System Generator (XSG) hardware co-simulation tool.
