Bm. Patre et al., Periodic output feedback control for singularly perturbed discrete model of steam power system, IEE P-CONTR, 146(3), 1999, pp. 247-252
In the paper a method is proposed to design a periodic output feedback cont
roller for a singularly perturbed discrete system. A state feedback control
ler designed from the singularly perturbed discrete system has been used to
compute output injection gain. This output injection gain has been used to
compute the periodic output feedback gain. The method does not require the
states of the system for feedback. The method is illustrated by a practica
l example of a fifth order steam power system.
