The document discusses control systems for an engraving machine. It has open and closed loop systems using sensors, actuators, and controllers. The engraving machine uses motors and lead screws to position the scribe in X, Y, and Z axes. The block diagram shows the x-axis position control system uses a proportional controller, which helps reduce steady state error and makes the system more stable while speeding up the response time of an overdamped system.

5. • The engraving machine shown in Figure uses two drive motors and associated lead
screws to position the engraving scribe in the X direction. A separate motor is used
for both the Y- and Z-axes, as shown:

7. • Controller used:
• Advantages of Proportional Controller:
1-Proportional controller helps in reducing the steady state
error, thus makes the system more stable.
2-Slow response of the over damped system can be made
faster with the help of these controllers.
