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.
