A novel model-free predictive mixed-sensitivity H∞control scheme is proposed and applied to grid-connected solarpower generation systems. The predictive sensitivity and thepredictive complementary sensitivity are defined based on the predictive model. The model-free predictive mixed-sensitivity H∞ controller is derived from input/output measurements to achieve an optimal predictive mixed-sensitivity performance using a maxmin optimization method. Then, a simulation system for solar power generation systems is established using SimPowerSystems. Finally, the simulations are conduced to show the effectiveness of the proposed model-free controller, which out performs the conventional proportional-integral and model-free linear quadratic Gaussian controllers in the tracking performance and the robustness of solar power generation systems.
