Sliding Mode Controller for a Dual Input – Single Output Converter in a Hybrid Power System

The presented work in this paper tackles the control problem with a Sliding-Mode Controller of a double input single output (DISO) DC–DC power converter that combines the power from a wind generator and a solar PV panel to supply a constant power load. The design procedure of the SMC is clearly developed with the appropriate control theory. In fact the proposed regulator is modulated to overcome the intrinsic unsettled behavior of the DISO converter in both off and on states, and to provide a high degree of output DC bus voltage regulation. Simulation results of the DISO converter for its reactions to load and DC line regulations illustrate the effectiveness of the SMC and its robustness to control the integration of a hybrid power system including diverse kinds of energy sources.
