DIGITAL CONTROL PROCESS WITH INVERSE FUNCTION TABLE MEMORY

A control process to keep input and output of the whole control system equal while measuring the input-output characteristics of the object to be controlled during the blanking time of the equipment in operation as the measuring mode period, by writing and memorizing the measured input as the data of a random access memory and the measured output as the address of the RAM, and by using the RAM as the inverse function table memory during the control mode period that follows the measuring mode period.
