摘要

CHARACTERISTICS OF A PROCESSING SYSTEM FIELD (13) CONTROLLED BY A CONTROLLER AUTONSINTONIZACION (10) are obtained by analyzing the response LOOP OPEN process variable (PV) to a phase APPLIED TO OUTPUT CONTROL CONTROLLER (II ). RESPONSE SYSTEM OF FIRST ORDER WITH REAL TIME DELAY IS USED TO APPROACH PROCESS FIELD OF HIGH ORDER OF THE REAL system response. DEAD TIME AND TOTAL TIME CONSTANT APPROXIMATION OF FIRST ORDER ARE DETERMINED. MAXIMUM CURVE PROCESS VARIABLE RESPONSE TO PHASE stored with an allotted time of occurrence and a process variable PROCESS OF ASSIGNED. The stored information is used to approximate the overall deadtime. In another embodiment, the stored information is assumed ARE ON DATA FROM AN ANSWER FOR SECOND ORDER IS a time constant ratio of 10: 1 and is used FINDING THE CONSTANT DETIEMPO SECOND ORDER ASSUMED THAT ARE USED TO FIND TIME CONSTANT FIRST ORDER. REALIZATION IN ANOTHER SECOND TIME CONSTANT FIRST ORDER IS DETERMINED USING A POINT OF CONVERGENCE FALLING WITHIN A DEFAULT ORDER BETWEEN REAL DATA RESPONSE AND THE APPROACH OF FIRST ORDER. PHASE NOT APPLY TO CONTROL OUTPUT (11) UNTIL THE VARIABLE PROCESS HAS REACHED Statehood INITIAL QUIET AND CALCULATING THE CURVE CESA WHEN THE VARIABLE RESPONSE REACHED PROCESS THE FIRST Statehood OF FINAL QUIETUD .SE DESCRIBED ALTERNATIVES TO DETERMINE TECHNICAL statehood of quietude.
