Abstract :
This paper introduces a robust nonlinear controller for a switch mode DC-DC boost converter. This innovative controller is employed to achieve the desired dynamic performance during steady state and transient operations. Step changes are considered in the load, the input and the desired output voltages, while unknown, but bounded disturbances corrupt the output load and the supply voltage. Practical stability of the converter is assured in the presence of those disturbances provided their maximum possible variation is known. Simulation results are provided to substantiate the applicability of the proposed control scheme.
