[Abstract]:To simulate human consciousness, the process of thinking is a very challenging science. In this paper, there is a significant difference in the information interaction between the one-way open loop mode of the traditional cognitive system and the comparison of the human cognitive things, and the difficult problem that the recognition rate and the correct rate can not be measured online in real time in the cognitive system, and the inaccuracy is discussed. Based on rough set theory, a model structure model and operation mechanism for establishing a cognitive object of uncertain information are explored based on rough set theory. Based on the generalized error theory and entropy theory, the multiple cognitive errors are explored. Based on the feedback control idea and the cognitive knowledge granularity computing tool, a cognitive intelligence operation mechanism with mimic feedback mode is established based on the feedback control idea and the cognitive knowledge granularity computing tool. The cognitive intelligence mechanism and the calculation model of the thinking information interaction model are compared. The main achievements of this paper are as follows: (1) research on the structure and operation mechanism of the imitative feedback cognitive intelligence system with uncertain information cognitive objects. The structure mode and operation mechanism of the three layer and three segment mutual coupling feedback cognitive intelligent system with repeated interaction mode are given, and the construction target of the imitation feedback cognitive intelligent system is given, the functional requirements and the operating mechanism are standardized, and the model structure is constructed for the imitation and recognition intelligent system of the uncertain information cognitive object. Method. (2) research on cognitive intelligence decision information system model of uncertain information cognitive object. Aiming at the problem that there is no common knowledge acquisition method that can adapt to all kinds of data in the current academic circle, the multi information fusion of uncertain information cognitive objects based on rough set is constructed and the intelligent decision information of supervised learning cognition is constructed. The system provides an index of cognitive knowledge fusion sufficiency and classification entropy function form based on characteristic simplicity. Under the uncertain information condition of finite domain, it provides a universal cognitive intelligence decision system model for the cognitive knowledge optimization representation of uncertain information cognitive objects. (3) the effect of uncertain cognitive process and Research on the generalized cognitive error evaluation system of cognitive results. In view of the fact that the current academic circles generally adopt the method of cognitive results reliability of posterior evaluation to meet the online real-time evaluation of recognition rate and correct rate in the cognitive system, the cognitive errors of uncertain information cognitive objects and uncertain cognitive process effects and cognitive results are constructed. The information system defines the uncertain cognitive process effect and the cognitive result error entropy based on the entropy function measure index. It does not determine the three generalized cognitive errors of the cognitive process effect and the cognitive result error entropy sequence and the cognitive knowledge granularity error, and establishes the online reality of the uncertainty recognition process effect and the cognitive result reliability. The time evaluation system provides a quantitative standard for the feedback cognitive intelligent adjustment mechanism. (4) the study of the imitating feedback cognitive intelligence mechanism of the uncertain information cognitive objects. The mimic feedback cognitive intelligence regulation mechanism which is poor online real-time measurement, defines the rules and calculation methods of the imitation feedback cognitive knowledge granularity, and establishes a multi-level variable knowledge granularity interlayer adjustment and the layer optimization model, and realizes the imitation feedback cognitive intelligent adjustment mechanism for the variable knowledge granularity of the uncertain information cognitive objects. Cognitive things provide an intelligent cognitive mechanism for the interactive process of information interaction. (5) the research and verification of the machine cognitive application of the off-line handwritten Chinese character image with a single goal and complete state. The recognition problem of the handwritten Chinese characters is large, the font font is numerous, the similar characters are many, and the writing style is different. The simulation feedback cognitive intelligence system of off-line handwritten Chinese character image with cognitive knowledge granularity intelligent adjustment mechanism is studied. The simulation experiment is carried out to verify the feasibility and effectiveness of this method by using the multi class Chinese character sample images of the SCUT-IRAC HCCLIB handwritten Chinese character image sample library as the cognitive object. The results show that this method has obvious advantages over the traditional one-way open loop method. A new practical application method is explored for the realization of "machine literacy" instead of "artificial literacy" for the off-line handwritten Chinese character image. (6) the machine cognitive application verification research on the burning state of industrial rotary kiln with multiple targets and complete state. Based on the imitation feedback cognitive intelligence method proposed in this paper, the imitation feedback cognitive intelligence system of the firing state of industrial rotary kiln based on flame image is studied based on the proposed simulation feedback cognitive intelligence method. The 2# rotary kiln firing zone of a cement plant is selected from the State Key Laboratory of the integrated automation of the process industry of Northeastern University. The flame image sample and the measured data are verified by MATLAB simulation experiment. The experimental results show that the method can excavate the characteristics of flame image from macro to micro and recognize the samples near the decision surface repeatedly, so as to realize the monitoring of the cement sintering process and the closed loop control of the clinker quality. A new method of engineering application is explored in place of "fire" instead of "fire". (7) a machine cognitive application verification study of human health status assessment of multi objective incomplete state. The imitation feedback cognitive intelligence system of human health state based on variable cognitive knowledge is studied. The feasibility and effectiveness of this method are verified by using MATLAB simulation experiments to verify the feasibility and effectiveness of this method. The results show that this method can be in different cognitive knowledge. To characterize health knowledge and fuzzy matching health indicators in the hierarchy of granularity, a new method is explored for the objective and accurate evaluation of human health status by "machine diagnosis" instead of "artificial diagnosis". (8) application verification research on intelligent recognition and tracking control of all weather photovoltaic power generation in single target incomplete state. The problem of photovoltaic cell tracking control is caused by nonlinear, non stationary, large intermittency and randomness. Based on the simulated feedback cognitive intelligence method proposed in this paper, the intelligent cognitive tracking control system for all weather photovoltaic power generation is studied, and a calculation method based on panoramic image variable granularity feedback is given. The experimental research is carried out to verify the feasibility and effectiveness of this method. The experimental results show that the model of the intelligent cognitive tracking control system of three layers and three segments of photovoltaic power generation can be based on the environment and system state of wind, snow, day, night, cloudy / rain and cloudy / cloudy. The cognitive knowledge carries out the corresponding control strategy and improves the photovoltaic efficiency based on the accurate calculation of the sun azimuth in the clear / multi cloud tracking control. A new intelligent control application method is explored to realize the high efficiency, energy saving and safe operation of the photovoltaic power generation system.
