Nonlinear Control Design Blockset

Strong Stabilization

Strong stabilization requirements (i.e., designing a stable controller to stabilize a system) may be considered a subset of the pole placement problem. Specifically, all poles of the controller are constrained to lie in the left half plane.

For real poles (e.g., s+a), simply enforce a lower bound of zero on the tunable pole (a) using the Lower Bound: editable text field in the Tunable Variables dialog box. Complex pole pairs defined as either (s+a+bj)(s+a-bj) or (s^2+as+b) should include the lower bound a,b>0.
