MECHATRONICS
--- Content provided by FirstRanker.com ---
(CAD/CAM)(For students admitted in 2013, 2014, 2015 & 2016 only)
Time: 3 hours Max. Marks: 60
--- Content provided by FirstRanker.com ---
Answer any FIVE questionsAll questions carry equal marks
*****
1 (a) With a block diagram, explain the elements of a mechatronic system.
(b) List the parameters to be considered for designing an intelligent mechatronic system.

2 An automobile industry needs a set-up for bending the sheet metal, as shown in dotted lines in
figure below, using two actuators A and B. The sheets are clamped manually. Develop a
pneumatic circuit for the above application. The cycle has to start once a ?start? button is pressed.

3 Briefly explain the motion control parameters that are required for the performance of the system.
4 Discuss briefly the following control modes.
(a) PI controllers.
--- Content provided by FirstRanker.com ---
(b) PID controllers.5 Device a PLC circuit for the following application: Consider a conveyor belt that is used to transport
goods from a loading machine to a packaging area. When an item is loaded onto the conveyor
belt, a contact switch might be used to indicate that the item is on the belt and start the conveyor

motor. The motor then has to keep running until the item reaches the far end of the conveyor andfalls off into the packaging area. When it does this a switch might be activated which has the effect
of switching off the conveyor motor. The motor is then to remain off until the next item is loaded
onto the belt.
