Consider a 500-gallon tank that needs to be filled when the level goes below 25 gallons and will stop when the level goes above 475 gallonsControl systems can be either open-loop or closed-loop; each one of them has its own.Advantages and problems. For the system described above:
1. Describe how you would implement it using an open-loop system.
2. Describe how you would implement it using a closed-loop system.
3. What are the type(s) of sensors required in each case?
4. Compare and contrast the potential problems that may arise in implementing the control system as an open-loop vs. a closed-loop system.
5. Assume that one of the pumps uses a ¼ hp DC shunt motor with an input voltage of 115 VDC That pulls 1.6 A running at 1,500 rpm. The field resistance for the motor is 600-ohm and the armature Resistance is 8.5-ohm. Find the constants Kemf and KT for this motor.
