In a sugar production, flow and the amount of cane fiber carried by cane carrier varies due to rnnon-uniformity of cane supply. The continuous variation of cane fibers flow and the level of canernfiber in chute during the cane juice extraction inversely affect the cane juice extraction efficiencyrnof mill. In this thesis we have developed algorithm for a three input fuzzy controller with an aimrnto maintain the cane level in chute and flow during cane juice extraction. The developedrncontroller generates signal that required controlling cane carrier motor speed depending upon thernvalue of cane level in chute, quantity of cane on rake carrier and flow rate. The three inputs fuzzyrncontroller is developed and simulated for six cases by using fuzzy logic toolbox of MATLAB. rnThe performance of the controller is compared in terms of disturbance rejection, transient andrnsteady sate performance. rnIt is observed from the simulation results that the average overshoot is 0%, rising time is 0.0817rnseconds and the settling time is 0.274 seconds with the proposed fuzzy controller whilernovershoot is 7.62%, rise time is 0.0513 second and settling time is 0.16 seconds with PIDrncontroller. Moreover, the robustness and disturbance rejection of the controllers is checked byrnparameter variation like time constant, delay time & DC gain and giving disturbance signal afterrnsettling time respectively. It is further observed that the proposed controller has betterrndisturbance rejection and more robust.
