Performance Analysis of Speed Control System using Voice Command and Ultra Sonic Sensor Based Approaches

This paper represents an experimental comparison of controlling the speed of the DC motor using voice commands and ultrasonic sensor-based control. The aim of the experiment was to compare the performance of both control methods in terms of speed control, distance measurement, and precision. An Arduino microcontroller, a DC motor, a microphone, and an ultrasonic sensor were used in the experiment. The Arduino was programmed to recognize certain keywords from the voice commands and adjust the speed of DC motor accordingly, in the case of voice command-based control. Regarding the ultrasonic sensor-based control, the Arduino was programmed to gauge the distance to an object using the ultrasonic sensor, and then modify the speed of the DC motor accordingly. The outcomes demonstrated that although both control methods could handle the DC motor's velocity, the ultrasonic sensor-based control performed better in terms of precision and distance measurement. However, the voice command-based control had the advantage of being more userfriendly and intuitive. The paper includes a detailed comparison of the performance of voice command-based control and ultrasonic sensor-based controlling of speed control of DC motor. It highlights the advantages and disadvantages of each method, and it can be used as a reference for selecting the appropriate control method for a specific application.
