Title:
AUTO-TUNING SYSTEM FOR HANDY CONTROLLER
Document Type and Number:
Japanese Patent JPS62280903
Kind Code:
A
Abstract:
PURPOSE:To reduce the burden of an operator by permitting the operator to execute an auto-tuning without the operator holding the titled device in a steady state. CONSTITUTION:A controlling means 11 compares a target value S0 and a controlled variable (output) PS from a process 3, and outputs an action signal CS in accordance with the deviation DS. A switching part SW 1 normally lies opposite to the position as illustrated. Consequently, the action signal CS from the controlling means 11 is given to an operation part 12 where an operation signal FS is formed and the process 3 is executed. With a tuning command given from the operator, the switching part SW 1 is automatically switched to illustrated positions according as a rise (turning on a power source) or a steady state (stable). Thus, the auto-tuning is started.
