y1 1 -0.7921

y2 1.226 -1

Name: DM

Static gain.

Equivalent Workflow in MATLAB

If you do not have a Simulink model of the control system, you can use LTI objects and

Control Design blocks to create a MATLAB representation of the following block diagram.

Figure 2: Block Diagram of Control System

First parameterize the tunable elements using Control Design blocks. Use the

tunableGain object to parameterize DM and fix DM(1,1)=1 and DM(2,2)=-1. This

creates a 2x2 static gain with the off-diagonal entries as tunable parameters.

DM = tunableGain('Decoupler',diag([1 -1]));

DM.Gain.Free = [false true;true false];
