The application of state feedback decoupling is proposed for the minimization of transients following small changes in real and reactive power levels in a turbo-alternator connected to an infinite bus through u transmission line. For an example. a ninth-order linearized system model is decoupled into two third-order single-input-single-output systems. The poles of these systems are optimally placed to satisfy n variety of design specifications. From the computational point of view, t his approach is far more attractive than that using state-variable or output feedback without decoupling. It also provides better insight into the problem.
