In response to a learning control start command from an external apparatus, an input switch for inputting a position deviation to learning control means and an output switch for outputting correction data from the learning control means are turned on, respectively, so that a position deviation is captured for each period. The position deviation is added to correction data fetched from a learning memory, and the result is stored as correction data in the learning memory. On the other hand, a value obtained by compensating the correction data fetched from the learning memory with a dynamic characteristic compensation element is added to the position deviation, and the result is inputted to a position control section. When a learning control end command is issued after the termination of a command pattern for an identical shape, the input switch and output switch are turned off, respectively.

A metal detector (40) used for identifying contaminants in packages (49, 50, 51) introduced into the metal detector by a conveyor. The detector (40) includes coils (1), a search head (2) and an analog to digital converter (3) that generates a reactive signal (13) and a resistive signal (14) in response to the presence of a contaminant in the region of the coils. A high pass filter (4) receives the reactive and resistive signals (13, 14). During a learning mode a sample product is introduced into the metal detector (40) to provide a representative product effect signal which is stored by the reactive learn memory (19) and the resistive learn memory (28). The learn memory values (29, 32) are forwarded to reference processors (20, 35) to provide a reference value which is subtracted from each product signal during a normal production cycle, thereby canceling the product effect caused by each individual package as it passes through the metal detector. The long term product effect is monitored during successive cycles (54, 62) composed of a series of packages undergoing normal inspection by the metal detector (40). A tracking processor (48) averages the product effect signal (57, 58, 59) produced by the individual packages (49, 50, 51) and continuously produces and updates a product effect trend signal (60) to be used by the reference processors as the signal to be subtracted from each product signal.
