ABSTRACT:
Control of a process in accordance with both optimal process values (t.sub.d), which may be fixed or slowly varying, and actual process output values (t.sub.r-1) generated during a previous interval (r-1) is accomplished by a differential process controller (10). The controller (10) employs two artificial neural networks (36 and 38), each generating a separate intermediate control vector for controlling the process in accordance with a separate one of the vectors t.sub.d and t.sub.r-1. A first summing amplifier (42) computes the difference between the intermediate control vectors and generates a differential control vector which varies accordingly. A second summing amplifier (44) sums the differential control vector, together with the output signal of the summing amplifier generated during the immediately previous interval (r-1), to generate a control signal c.sub.r for controlling the process.
