University of ColimaChemical Science FacultyMetallurgical chemical EngineeringTopic: Automatic control of pH in a buffer using fuzzy logic Brian Cabrera Miranda8DintroductionThe control of pH buffers is very difficult because these solutions are limited to acidity or alkalinity when these are exceeded soar so that the research field is very wide in this project will be used fuzzy logic to control pH with the addition of acids and bases by hoses which are subject to peristaltic pumps
working techniquesI will work with a closed loop system to look for the slightest mistake
PID
PID: Action proportional-integral-derivative representing the following expression
By means of a fuzzy logic system, the following values of constants are searched
Once the error found the disturbances will be very low stable system
system disturbance
This must be very efficient for any changes required in the high or low pH adjusted to follow any path to any system
CONCLUSION This method can be brought to the industry, industries that require good control of pH in the process, these in turn seek pH control methods. The buffer solutions have different properties to acidic or basic solutions and are currently being studied to eliminate control problems
