ABSTRACT
This book chapter has reported various application-based case studies of a peristaltic pump with optical measuring unit. The present study is intent on designing an efficient controller to deliver a constant flow rate of peristaltic pump for precise fluidic applications considering all the components. An optical sensor-based measurement system is proposed for flow sensing of the pump. A pump model based on input–output data set along with modelling uncertainty has been considered here. Internal model principle-based repetitive control (RC) is featured here to deal with the periodical load disturbances encountered by the pump and which is to be attenuated on a desired level for precise flow rate control of the same. The RC law is modified with an augmented adaptive control law which corrects the variations in the flow rate based on the parameters updated by that control law by compensating a varying frequency disturbance signal. Simulation study has been carried out in MATLAB.
