In this manuscript, based on Smith predictor control scheme for unstable process in industry, an improved double loop control model is proposed for chemical unstable processes. Inner loop is to stabilize integrating the unstable process and transform the original process to first-order plus pure dead-time dynamic stable process. Outer loop is to enhance the performance of set point response. Disturbance...
Fuzzy measure is a kind of set function which can represent the interaction of IF-THEN rules in reasoning, and fuzzy integral is decision tool in information fusion and process control problem. Although the fuzzy cognitive map model is an effective approach in reason process and the intuitionistic fuzzy cognitive map model introduces intuitionistic fuzzy set which uses the hesitancy as the indeterminacy...
Based upon the summary of software project management, this paper concretely puts forward the project works, such as integration management, risk management, requirements management, epiboly management, quality management, configuration management, resources management and schedule management, and clearly points out that we should pay attention to project process inspection, enhance project measurement...
This paper ,mainly give a introduce to control strategy in ingredient control system, because of weighing process of raw materials is a nonlinear, time-varying and uncertain production process that is unable to get accurate mathematical model, therefore, the fuzzy control algorithm is used in weighing system .With "intelligent learning control model" applied to the system, it realized the...
To solve the shortcomings of low cutting accuracy and curling edges of the traditional slitter. So the paper raised a tension control system without sensor on the basis of analysing process of the slitter. It realized the flexible adjustment of the cutting parameters. The materials went in and out of cutting rolls used servo motor constitutional main-secondary pulling mode. By controlling the difference...
