LQG/LTR control system design for a low-pressure feedwater heater train with time delay [PDF]
[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society, 2002 An LQG/LTR control system design is formulated for a nuclear reactor feedwater heater train with output time delay. This approach involves factoring the feedwater heater train plant into nonminimum and minimum-phase components to allow the design of a robust controller for the minimum-phase component of the plant using the LQG/LTR technique.
