Adaptive robust control of the EBR-II reactor

Simulation results are presented for an adaptive H∞ controller, a fixed H∞ controller, and a classical controller. The controllers are applied to a simulation of the Experimental Breeder Reactor II primary system. The controllers are tested for the best robustness and performance by step-changing the demanded reactor power and by varying the combined uncertainty in initial reactor power and control rod worth. The adaptive H∞ controller shows the fastest settling time, fastest rise time and smallest peak overshoot when compared to the fixed H∞ and classical controllers. This makes for a superior and more robust controller
