AbstractIn the past century overhead cranes have gained a very important role in industries andports One of the most important parts that need to be repaired is the wheels of the bridge The bevel of the bridge is due to the fast wearing of wheels and rails So it is vital to eliminate yaw motion of the bridge In this thesis the factors causing yawmotion of bridge has been studied and the dynamic behavior of trolley and bridge has beenpresented by differential equations The previous methods of controlling the bridge of overhead cranes have been simulated byMatlab Simulink It is easily seen in a bad condition these methods are not able toeliminate the bevel motion of bridge properly Finally a new controller has been presented In this method four limit switches are appliedto measure the distance between the rail and wheel axes Different outputs of limitswitches represent different states The controller produced proper signals to control thebridge in each case Complete simulation result of a 5 ton overhead crane bridge with two induction motorsand PWM inverter are presented to validate the effectiveness of the proposed controller finally the performance of scalar and vector controllers in this system have been compared
