PURPOSE:To apply a mountaineering method by determining a slope formula in accordance with measured values of process variables to manipulate process for climbing by a certain height in a prescribed direction, and setting certain limitations periodically to each process variable. CONSTITUTION:Measured values (x) and (y) of process variables are outputted from detectors 3 and 6. An operator 1 receives process measured values xi and yi and an efficiency variable zi inputted through sampling switch SW1-SW3 and calculates a slop formula z=ax+by+c by the regression calculation using the method of least squares. An operator 2 receives this slope formula (z) through a sampling switch SW4 and receives variables (x) and (y) and limit constants DELTAx-DELTAz inputted from the external and performs the mountaineering calculation and gives manipulated variables to controllers 4 and 7 through sampling switches SW5 and SW6. Controllers 4 and 7 drive operation ends 5 and 8 on a basis of input manipulated variables and display process variables (x) and (y). This operation is repeated at a prescribed period, thereby making mountaineering possible while always searching. |
