+Discusses:
+
+-   When to use multivariable control and when not to?
+-   Two major issues with implementing multivariable control: **gain scheduling** and **integrator wind up protection**
+
+> Inline simple gain and phase margin measured for SISO, "robustness" determination of multivariable control requires complex analyses using **singular value techniques** and **Monte Carlo** simulations.
+
+**When to use multivariable control**:
+
+-   System has high input/output coupling and not much separation between loop bandwidth
+-   System is complex with large number of states
+-   When sequential SISO loop closure will not meet performance requirements
+
+Importance of having a mechanism to limit the control rate in the synthesis process.
+The control rate should be weighted appropriately in order to not saturate the system and stay in the linearity regime.
+
+-   importance of scaling the plant prior to synthesis and also replacing pure integrators with slow poles
