Abstract

The adaptive multivariable command system uses the time in the data input to command output process is accounted for. For non-linear command processes with dead time, the system can be protected from instability. The system process (5) is modelled by a parallel electronic analogue (6) and uses another slave circuit model as reference (2). Input commands (Z) pass via a variable matrix (3) to a summing unit (4) fed by the feedback loop from the parallel model output (18) and the reference output (7). The reference output with dead time delay added (9) is compared with the actual process output in a comparator (10) whose output (12), with that of the model (18) and a delayed input sample (15) is treated by an adaptor unit (14) so as to minimise the error voltage at the comparator (e) via a variable matrix (22).
