This method for calibrating coefficients of an observer of a variable state comprises: the measurement (50) of a variable zk of the physical system at N different instants, this variable zk being a function of the state variable xk, the determining (54) of a vector p of coefficients which minimizes the following criterion in complying with a predetermined setΔof constraints: { f ( p ) =∑k = 1 N z k -φ ( x ^ k , p ) 2 } where: {circumflex over (x)}k is the estimation of the variable xk built by the observer calibrated with the coefficients of the vector p at the instant k,φis a known function which links the estimation {circumflex over (x)}k to an estimation {circumflex over (z)}k of the variable zk,∥︀. . .∥︀2 is a norm, and the constraint or the constraints of the setΔdictate that the trajectory of the variable zk should be included in a corridor of uncertainty situated on either side of the trajectory of the estimation {circumflex over (z)}k at least for the majority of the instants k.
