A power generator station is running by steam turbines to generate electricity. The frequency of the produced power is controlled using PI controller which works within the range 30- 70 Hz and it was set to standard frequency set point of 50 Hz. The proportional gain of the controller is 0.45% and the integral range is 0.20%. If the frequency fluctuates to 49.75 Hz, what is the overall controller output after 5.0 sec if the initial out pout is 20%?

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
