Feedforward and Feedback DC Motor Control Methods of Control Systems

Abstract

DC motors are the most popular transducers used in the industry. Their versatility allows them to be used and configured in many different varieties, therefore, it is important to know which method to use for controlling them as there are currently many designs for different DC motors and different applications. This paper focuses on comparing the feedforward and feedback motor control methods. The DC motor design that the paper will consider is a voltage-controlled armature driven DC motor. The group will use MATLAB to simulate the two methods and will implement them to the motor. In addition to that, setpoint command tracking will also be a parameter to be considered in determining the performance of the two methods. Furthermore, a comparison of their performance against each other will be done by introducing a load disturbance in the armature-controlled DC motor in order to determine their sensitivity to possible noise in the system.
