OP a la Control Systems

Actuators: I remember the first time I was in the common room. The GSecs introduced themselves. The Warden was there. And then it all started. Everything was set into motion. Who are the actuators? We all know!
 
Motors: I always wondered why second years always did the brunt work. Whether it was making the diyas for Illu, winning the GC or shifting rooms, everything was done by the 2nd years. Then I realized it is all part of a system: a control system.
 
Feedback: Now this is where things get interesting. The unique thing about OP in Nehru Hall is that it is a closed loop system. Not an open loop like in many other halls. If things got bad, OP stopped for a day or two and then the 2nd years themselves went and pleaded their seniors to start things again. Perfect mechanism!
 
Reference: We had 3 common room meetings every week which ran for a duration of 3 hours each. This is the minimum expected of you to become a Nehruite!
 
(Pressure) Sensors: “Was it too much or anything? This is for your own good.” “No sir, peace. Only xyz seemed to be under some amount of load. (Resistive, capacitive & inductive behaviour all taken into account) ”
 
System Output: Nehruite!
 
Note: If some things didn’t make sense, consider it like a 2 port network. All you are concerned about is the input (a non-Nehruite), the output (a Nehruite) and the transfer function (tempo).
