Design of Observer

According to the control theory, the state observer (state estimator) is known as the term that gives the measures of the internal state of any particular absolute system. The state observer uses the input as well as output of the system for measuring the internal state. It is standard computer-implemented and delivers the basis for numerous practical applications.

Question

Example Problem 4-1, (page 141). [Ref.1]:
The shaft shown in Figure 4-7 is supported by two bearings and carries
two V-belt sheaves. The tensions in the belts exert horizontal forces on the shaft,
tending to bend it in the X-Z plane. Sheave B exerts a clockwise torque on the
shaft when viewed toward the origin of the coordinate system along the X-axis.
Sheave C exerts an equal but opposite torque on the shaft. For the loading
condition shown, determine the principal stresses and the maximum shear
stress on element K on the front surface of the shaft (on the positive Z-side) just
to the right of sheave B, Follow the general procedure for analyzing combined
stresses given in this section.

A DC servomotor drives the y-axis of a NC milling machine table. The motor is coupled to the table lead screw with a gear reduction of 2:1. The lead screw pitch =5 mm/rev. An optical encoder is directly connected to the lead screw. The optical encoder emits 100 pulse/rev. To execute a certain programmed instruction, the table must move from point (25,28)mm to point (155,275)mm in a straight-line trajectory at a feed rate = 200 mm/min.
