1.
What are Mia and James mainly discussing?
A plan for a marketing campaign
A report on employee attendance
The purchase of new office equipment
The settings and testing of a PID control loop
Explanation:
They discuss PID settings such as proportional, integral, and derivative gains, sampling time, and testing the system after tuning.
2.
What derivative gain does Mia ask James to try?
2.5
1.0
0.3
0.1
Explanation:
Mia says, “Yes, try increasing it to 0.3 and watch the response.”
3.
What does Mia say about the loop sampling time?
It is too high and should be lowered
It is acceptable at 0.5 seconds
It has not been set yet
It must be changed before testing
Explanation:
Mia states that the loop sampling time is set to 0.5 seconds, which is acceptable.
4.
What can be inferred about the proportional gain being set to 2.5?
Mia thinks it may make the system respond too aggressively
Mia believes it is too low to have any effect
James plans to decrease it immediately
The system is already stable and needs no tuning
Explanation:
Mia says the proportional gain seems a bit high and might cause overshoot, which suggests it may make the system respond too aggressively.
5.
What will James most likely do after the tuning changes are made?
Order a replacement controller
Increase the sampling time to 1.0 seconds
Record the temperature response and check for steady-state error
Stop the system permanently
Explanation:
James says he will record the temperature response after changes, and Mia also asks him to check for any steady-state error.
