A unified Smith predictor approach for power system damping control design using remote signals

This brief illustrates a control design procedure for handling time delays encountered in transmitting the remote signals in power systems. A unified Smith predictor (USP) approach is used to formulate the control design problem in the standard mixed sensitivity framework. The solution to the problem is sought numerically using linear matrix inequalities (LMIs) with additional pole-placement constraints. The predictor based method is applied for designing a damping controller for a prototype power system. Simulation results show that the controller performs satisfactorily even though the feedback signals arrive at the control site after a finite time delay

Abstract—This brief illustrates a control design procedure for handling time delays encountered in transmitting the remote sig-nals in power systems. A unified Smith predictor (USP) approach is used to formulate the control design problem in the standard mixed sensitivity framework. The solution to the problem is sought nu-merically using linear matrix inequalities (LMIs) with additional pole-placement constraints. The predictor based method is applied for designing a damping controller for a prototype power system. Simulation results show that the controller performs satisfactorily even though the feedback signals arrive at the control site after a finite time delay.
