Title:
技術的プロセスを調整および制御する方法
Document Type and Number:
Japanese Patent JP2004529416
Kind Code:
A
Abstract:
A method for controlling and driving a technical process executed in time by applying at each time t instructions Ci(t), leading to a measurable but not observable result R(t) and generating a plurality of observable quantities distinct from the result R(t) whereof at least two are independent Gj(t), which consists in: measuring at least two independent observable quantities Gj(t), Gp(t); with a predictive model M, or a set of models, whereof the variables comprise the at least two independent observable quantities, calculating an estimation Res(t)=M(G1(t), Gp(t) of the result R(t); using a drive law L, whereof the input variable is the estimated result Res(t) calculating new instructions Ci(t+1), applicable for time t+1; and replacing the instructions [C1(t), Cn(t)] by the instructions [C1(t), Cn(t+1)]. The method for controlling and driving a technical process is applicable to spot welding.
