L₁-Adaptive Robust Control Design for a Pressurized Water-Type Nuclear Power Plant

“…Several control design techniques, for example, state feedback assisted control (SFAC) [1]- [6], H ∞ control [7]- [10], model predictive control (MPC) [11]- [16], sliding mode control (SMC) [17]- [24], and different soft computing techniquebased controls [25]- [31] have been proposed in the last two decades to handle uncertainties and disturbances. In the earliest work, the notion of an SFAC has been suggested to boost the local stability of a conventional control by adding a state-feedback compensation [1].…”

“…To control reactor power with enhanced robustness as compared to the conventional LQG control, H ∞ based techniques have been suggested [7]- [10]. Robust MPC techniques have been developed to handle various constraints in an uncertain NPP system [11]- [16]. Robust control design techniques using SMC are proposed to guarantee robustness towards uncertainties coming from the input channel [17]- [24].…”
