The inertia /, in the block diagram is the equivalent inertia of the entire system, as felt on the motor shaft.

  1. Assume that the motor inductance is very small and set L = 0. Compute 4, obtain the transfer function 0(s)/0r(s), and compute the values of the control gains Kp and Kj to meet the following specifications: < = 1 and
  2. t = 0.5 s.

  • Use the MATLAB tf function to create the model sysl from this transfer function.
  • Using the values of KPand Kj computed in part (a), and the value L = 0.015 H. obtain the transfer function 0(j)/0r(5) and use the MATLAB t f function to create the model sys2 from this transfer function.
  • Use the MATLAB step (sysl, sys2) function to plot the unit step response of both transfer functions. Right-click on the plots to obtain the maximum percent overshoot and settling time for each. How close are the two responses? What is the effect of neglecting the inductance?

    A torque of magnitude T = 12 kNm is applied to the end of a tank containing compressed air under a pressure of 8 MPa (Figure Q1). The tank has a 180 mm inner diameter and a 12 mm wall thickness. As a result of several tensile tests, it has been found that tensile yeild strength is σy = 250 MPa for thr grade of steel used. Determine the factor of safety with respect to yeild, using: (a) The maximum shearing stress theory (b) The maximum distortion energy theory T Figure Q1
