Управление температурным режимом стадий ацеталирования поливинилового спирта

The analysis process atsetalirovaniya polyvinyl alcohol as a control object. The process atsetalirovaniya polyvinyl alcohol takes place in batch mode. Chemical transformation is carried out in isothermal mode, so you need to stabilize the temperature. In the case of a periodic process, the chemical reaction rate decreases with time due to the exhaustion of the initial substances, which changes the heat balance of the process and therefore the object of control parameters. You can solve this problem by adjusting the temperature with fuzzy logic. Temperature control is performed by a cascade scheme. Internal regulator is a regulator of the cascade of water flow, and an external controller is a digital temperature controller, the controller generates jobs coolant flow with fuzzy logic. If the deviation of the temperature of the reaction mass from the given value does not exceed the permissible value, the job controller coolant flow rate does not change.
