Design And Implementation Of Speed And Torque Controller For Dc Motor
Résumé: Electric drives have many applications in different areas such as industry, transport, agriculture and domestic. The operation of electric drives are selectively regulated and made partly or fully automatic to increase the productivity and efficiency of the industry. The dc drives still play a significant role in modern industrial drives due to its higher performance, reliability, adjustable speed control etc. This project aim is to design and implement a speed and current controller for PMDC motor with a high performance. Using the chopper as a converter, the speed of DC motor may be controllable. The chopper firing circuit may get signal from controller in order to supply variable voltage to the armature of the DC motor at the desired speed. The controller consists of two different control loops, current control and speed control. The used controller is Proportional-Integral type due to its fastness. The current and speed controller is designed by taking into consideration the high stability even at high speed control of DC motor. The simulation of model is investigated and analyzed using LABVIEW and Simulink/MATLAB under different speed and torque conditions.
