balreal
Gramian-based balancing of state-space realizations.
Syntax
[sysb, g] = balreal(sys)
[sysb, g, T, Ti] = balreal(sys)
Input argument
sys - LTI model.
Output argument
sysb - LTI model.
g - Diagonal vector of the balanced Gramian matrix.
T - State similarity transform matrix.
Ti - State similarity transform inverse matrix.
Description
balreal(sys) calculates a balanced realization, denoted as sysb, for the stable segment of the linear time-invariant (LTI) model sys.
This process is applicable to both continuous and discrete systems. If sys is not initially in state-space form, the function automatically converts it to state space using ss before proceeding with the balanced realization.
