Functional In/Out Diagram

The functional diagram above illustrates the main components of the system and their interactions:

Input: The inputs to this system include control signals for the two motors, Motor1 and Motor2, in the form of PWM (Pulse Width Modulation) signals. These signals regulate the speed and torque of the motors, ensuring precise control over the movement of the system. Additionally, the actuator's displacement in millimeters is another input parameter that allows for adjustments to the belt's tension. These inputs enable dynamic manipulation of the mechanical components to achieve the desired performance.

Process: The process begins with the motors driving the system by interacting with the tension belt. The motors apply force through the pulleys and turning wheel to control the movement of the belt. An actuator with a load cell is integrated into the system to measure the tension applied to the belt in real-time. As the motors rotate, the belt speed and tension are influenced by the motor speeds (Motor1 speed and Motor2 speed) and the actuator's displacement. The load cell provides feedback on the belt tension, allowing for continuous adjustments to maintain optimal operation. This ensures smooth and efficient mechanical performance.

Output: The outputs of this system include the rotational speeds of Motor1 and Motor2, the speed of the belt, and the tension applied to the belt. These outputs are crucial for monitoring the system’s performance in real-time. By providing precise data on motor speeds, belt speed, and tension, the system allows for accurate control and evaluation of its efficiency and stability. This feedback mechanism ensures that the system operates reliably under varying conditions.
