| 摘要 |
The invention concerns a method for controlling and driving a technical process executed in time by applying at each lime l instructions C1(t), leading to a measurable but not observable result R(t) and generating a plurality of observable quantities distinet from the result R(t) whereof at least two are independent Gi(t), which consists in: measuring at least two independent observable quantities Gi(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 C1(t+1), applicable for time t+1; and replacing the instructions C1(t), ... Cn(t) by the instructions C1(t), ... Cn(t+1). The invention is applicable to spot welding. |
