Problem-5 In each of the following examples, indicate at least one (unknown) input that should be measured and used for feedforward control to improve the accuracy of the control system. Justify your selections for each item via providing the corresponding reasoning. a) A servo system for positioning a mechanical load. The servo motor is a field-controlled de motor, with position feedback using the pulse count of an optical encoder and velocity feedback using the pulse rate from the encoder. b) An electric heating system for a pipeline carrying liquid. The exit temperature of the liquid is measured using a thermocouple and is used to adjust the power of the heater. c) A room heating system. Room temperature is measured and compared with the set point. If it is low, the valve of a steam radiator is opened; if it is high, the valve is shut. d) An assembly robot that grips a delicate part to pick it up without damaging the part. A welding robot that tracks the seam of a part to be welded. e)
