SELF-STATE DEVELOPMENT PROCEDURES FOR THE FUNDING OF A PHYSICAL SYSTEM.

摘要

In a physical system to be piloted in discrete mode, an outlet value $g(U) is related to a control variable $g(b) by the equation: $g(U) = A6?.$g(U) + K1?.$g(b) + $g(e), in which at least one of the parameters A6? and K1? is unknown. If Yk? is the value of $g(U) at time k and if $g(b)ck? is the control command produced by the guide calculator at that time, there exist three polynomials in q?-1 (delay operator), E, A', N with constant coefficients determined in advance, such that at any time, following preliminary filtration (index F) by an at least first-order polynomial in q?-1, the following approximation holds: (E'.Yk?)F? = (A'.Yk?)F?.A6? + (N'Bck?)F?.K1? + noises. At each step of piloting, the terms of this linear combination in A6? and K1? are calculated, at least this unknown paramater is estimated by means of a parametric variation model, and a control signal for one or more harmonic components of selected amplitudes and pulsations is added, for these instantaneous values of the parameters, by interpolation in a pre-established table which ensures that the tractions are maintained within predetermined ranges.
