WebCompare the motor inertia to the load inertia above. a. If its value is <10% of the load inertia, you are done. b. If its value is >10% of the load inertia, an iterative step must be performed to adjust the required torque by this amount. The extra torque required should be a direct ratio of additional inertia. c. WebFor example, if we wanted to obtain a complex conjugate pole pair with a damping factor ζ = 0.707, indicated by the gray rectangles, the lengths of the three vectors that connect the “open-loop” poles (i.e., those with k I = 0) with the desired pole location can be used in the magnitude component of Eq. (12.9) to solve for k I.
