Abstract Nowadays environmental problems high energy costs and reduction in the fuel resourceshave become as the reality of life that makes the study of all energy consuming processes inthe way of improving their total efficiency inevitable In every industrial process which isbased on fluid transfer from one pressure level to a higher level pumps are used as a mainpart and for this reason pumps are considered as a primary consumers of energy In this thesis separate parts of a pump induction motor drive and also the loss model foreach part are studied and for each part a model is proposed which although with suitableprecision it doesn t need any complicated and extra calculations Hence in order to model thepumps and the hydraulic system which is a nonlinear and complicated system the neuralnetwork is applied Different efficiency optimization approaches in the induction motor driveare studied and it is shown that an appropriate approach for efficiency optimization in thepump induction motor drive is the minimum loss search approach Of the criticisms on thisapproach are its slowness and the oscillation round the optimum point The search tablesapproach also exists as a controlling approach which is based on practical experiment Of thecriticisms on the search tables approach is that in practice the number of test points arelimited and also if the parameters of motor and load would change over the time these tablesmust be modified and prepared again In the present thesis a fuzzy search control approach is proposed in the pump inductionmotor drive The proposed controller by integrating the search table approach with theminimum loss search approach and by considering the necessary strategies in design couldreduce the problems existed in both approaches
