Abstract: The disclosure discloses a low-loss transmission line structure, which belongs to the field of radio frequency transmission lines and includes at least two metal layers stacked in a vertical manner. A dielectric layer is filled between the metal layers. The metal layers include a signal transmission strip in a middle portion. Ground strips are provided on both sides of the signal transmission strip. Through holes are evenly distributed on the dielectric layer, and the signal transmission strips on each of the metal layers are connected through the through holes to form a signal transmission line. The ground strips on each metal layer are connected through the through holes.

Abstract: A reduced instruction set processor based on a memristor is provided. The memristor is a non-volatile device using a resistor to store “0” and “1” logic while implementing “implication logic” through applying a pair of voltages VCOND/VSET. Various data operations, logic operations, and arithmetic operations may be implemented based on the implication logic. The memristor is a computation and memory fusion device having great potential. A computer processor based on the memristor also becomes the research direction of the next-generation computer processor. The computer processor based on a memristor is designed according to the memory and computation fusion characteristic of the memristor. The processor is different from a traditional computer that must use a special memory and a calculator, and fuses computation and memory. Compared with a traditional computer, the speed, parallelism degree, and power consumption of the computer processor based on the memristor are greatly improved.

Abstract: The present invention provides a thermoelectric cooperative control method for the SOFC system based on fractional order sliding mode variable structure, comprising the following steps: S1, collecting parameters of system states and output under combinations of different input parameters of the SOFC system, acquiring an influence function of steady-state power, temperature, efficiency response characteristics and bypass valve opening BP within a full load interval on efficiency optimization, as well as an efficiency optimization function within a specified load switching interval and under a time-delay condition; S2, acquiring a local optimal steady-state operation function, a global optimal function under the steady state developed and formed, and a power tracking function with different switching intervals and different time-delay conditions; S3, calculating a sliding mode interval; S4, calculating a series reaching law function according to optimization functions; S5, eliminating chattering of the series reaching law function through a fractional order optimization method, and solving the reaching law by calculation. The present method can provide precise, flexible and stable control, greatly speed up the switch process, overcome time-delay feature of the great inertia of the SOFC system, and realize fast load switching.
