Claim:
Method of regulating and controlling a technical process which is executed in time either in a continuous manner or in a discontinuous manner by applying at each time t desired values {C 1 (t), . . . , C n (t)} leading to a result R(t) which is measurable but not observable and generating a plurality of observable quantities separate from the result R(t) of which at least two are independent {G 1 (t), . . . , G m (t)}, characterized in that: at least two independent observable quantities G 1 (t), . . . , G p (t) from the plurality of the observable quantities {G 1 (t), . . . , G m (t)}, are measured, with the aid of a predictive model M, or a set of models, of which the variables include the at least two independent observable quantities, an estimate R es (t)=M(G 1 (t), . . . , G p (t)) of the result R(t) is calculated, with the aid of a control law L of which the input variable is the estimated result R es (t), new desired values {C 1 (t+1), . . . , C n (t+1)}=L(R es (t)) are calculated which are applicable for the time t+1, the desired values {C 1 (t), . . . , C n (t)} are replaced by the desired values {C 1 (t+1), C n (t+1)}, and the predictive model M is a statistical adjustment model depending upon parameters {θ 1 , . . . , θ p } which constitute a parameters vector θ adjusted on a learning base B ap consisting of all of the desired values, the measurements of the observable quantities and the measurement of the result for a plurality of successive executions of the technical process.
