What is it about?
A multi-input/multi-output linear model of the system, as seen from this unit, is obtained by least-squares identification. On the basis of this model a multivariable controller is designed, by minimizing a quadratic performance index using the dynamic programming procedure. This local controller employs output feedback, and provides integrated control of the exciter and turbine-valve inputs.

Why is it important?
Using output feedback control in the complex power system. This overcomes the drawback of using state feedback control which needs measurements of inaccessible or noisy state variables.
Perspectives
This paper provides enhanced optimal control that can be applied in practical power systems.
