TL;DR: The principle of operation, the theoretical analysis and the experimental results of a laboratory prototype for N(N2/N1) = 2 and n = 2 stage in about 260W with operating at 40kHz are provided.

TL;DR: In this article, a multi-objective technique has been proposed for optimal analysis of three different candidate heat pump solutions including the vapor compression cycle (VCC), trans-critical R744 cycle, and Peltier device to determine which one gives the best configuration and better performance on a hybrid heat pump and fuel cell-based micro-CHP system.

TL;DR: A robust NN (RNN) control scheme is presented to eliminate uncertainties to improve the tracking robust stability and overcome the undesired influence of uncertainties based on the nonlinear system dynamic model under continuous-trajectory tracking mode.

TL;DR: Simulation and experimental results show that SMO has accurate speed and position tracking performance, the system’s chattering is significantly reduced, the control precision is excellent, and the introduction of adaptive sliding mode controller enhances the robustness of the system.

TL;DR: The hydrogen energy system based on the multi-energy complementary of renewable energy can improve the consumption of renewable energies, reduce the adverse impact on the power grid system, and has t... as discussed by the authors.
