Assignment Help Mechanical Engineering

Reference no: EM131200016

In each of the following examples, indicate at least one (unknown) input, which should be measured and used for feed forward control to improve the accuracy of the system.

(a) A servo system for positioning a mechanical load. The servo motor is a fi eldcontrolled dc motor with position feedback using a potentiometer and velocity feedback using a tachometer.

(b) An electric heating system for a pipeline carrying a 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, a valve of a steam radiator is opened; if it is high, the valve is shut.

(d) An assembly robot, which grips a delicate part to pick it up without damaging the part.

(e) A welding robot, which tracks the seam of a part to be welded.
