Generate a signal composed of two square waves, the first has a 14 Hz and the second has a 55 Hz frequency. Both waves are sampled at 2 kHz for 200 ms. Duty cycle for the first wave is 40% while the second’s is 35%. Show the signal with and without adding white Gaussian noise with a variance of 1/100 in matlab

1 - Is PID control used in Feed Forward or Feed Back control?
2 - We have a controller, and every time the Operator changes the Set Point, the controller responds, and gets the process sorted out. Now, somewhere, we have read that load disturbances needed to be considered in processes, as well. How will this controller react, if there is a load disturbance, and not a Set Point change?
