Hydrazine Concentration Estimation in the Secondary Circuit of a Nuclear Power Plant: a IQC LPV approach

This paper addresses the design of a new linear parameter varying estimator, to estimate the hydrazine molar concentration in the secondary circuit of a nuclear power plant. The method uses dynamic shaping filters of arbitrary order, to formulate the estimation performance objectives. The theory is based on L-2-gain synthesis, based on uncertainty characterization via static integral quadratic constraint multipliers. It is shown that the problem can be formulated as a semi definite programming problem, that can be solved efficiently using numerical solvers. The proposed approach is applied to real data, coming from a nuclear power plant located in France. The obtained results demonstrates the efficiency of the proposed approach.
