Question subject is Controls systems and automation

http://newton.ex.ac.uk/teaching/CDHW/Feedback/OvSimForm-gen.html note the initial values used by the simulator and the output produced. For BOTH ON-OFF and PID control,

(a) sketch (or print copies) of the effect of changing the following parameters from their existing value (resetting them to the original after every change has been recorded):

(i) Increasing the proportional control by a factor of 10.

(ii) Decreasing proportional control by a factor of 10.

(iii) Increasing the integral control by a factor of 10.

(iv) Decreasing integral control by a factor of 10.

(v) Increasing the derivative control by a factor of 10.

(vi) Decreasing derivative control by a factor of 10.

(vii) Increasing the hysteresis by a factor of 10.

(viii) Decreasing hysteresis by a factor of 10.

(ix) Increasing the system lag by a factor of 10.

(x) Decreasing system lag by a factor of 10.

(b) Explain your results.
