Tuning Goals

Basic control objectives include bandwidth (response time) and stability margins. Use the

"MinLoopGain" and "MaxLoopGain" goals to set the gain crossover of the outer loops

between 0.5 and 5 rad/s. Since all loop variables are expressed in degrees, no additional

scaling is needed.

R1 = TuningGoal.MinLoopGain({'Phi_deg','Alpha_deg','Beta_deg'},0.5,1);

R1.LoopScaling = 'off';

R2 = TuningGoal.MaxLoopGain({'Phi_deg','Alpha_deg','Beta_deg'},tf(50,[1 10 0]));

R2.LoopScaling = 'off';

Use the "Margins" goal to impose adequate stability margins in each loop and across

loops. This goal is based on the notion of disk margins which guarantees stability in the
