| Abstract | ||
| The research presents a closed loop control system to control the speed of a dc motor using cosine control method. The method generates a synchronized cosine voltage with an error dc level. The error level represents the difference between a voltage which represents actual speed and a voltage proportional to reference speed. The proposed method proved to be effective in controlling the speed since it gives a linear relationship between the output voltage and the control voltage .Adequate torque- speed characteristics were obtained. The proposed system controls the speed by varying the control voltage and hence the average armature . A second loop which measures the current of the armature , compares it to the reference (rated) value and enable the AND for normal value of current or disables for over current conditions. This method can be extended to drives operated from three phase converters. | ||
