Provide the ideal gain scheduling for Figure 12.16 as a function of Q.

DATA FROM FIGURE 12.16

COULOMB fCOULOMB SSTICTION Force -ISTICTION Velocity Coulomb friction + Stiction + Viscous

 Assume inertia varies with theta as follows:

damping Total friction

where JM is the motor inertia, JL is the load inertia, and R is the length of both arms connected to the elbow. Assume that the nominal gain is defined as the gain when Q = 0.
