<p>A control parameter adjustment method, which is used in plants having a plurality of PID control loops and a support server connected to the plants via a communication network, involves the following procedure. In other words, in the plants: information regarding the plurality of PID loops is acquired; operation levels, measurements, targets and disturbances are extracted from the acquired information; and time-series data spanning a prescribed time of the extracted operation levels, measurements, targets and disturbances are sent to the support server via the communication network. In the support server, control performance is diagnosed for each PID control loop on the basis of the time-series data, and PID control loops for which the control performance does not meet a preset condition are assessed, and the control parameters of the assessed PID control loops are identified by referencing the time-series data of the assessed PID control loops. Moreover, in the plant, the control parameters of the assessed PID control loops are updated on the basis of the identified control parameters.</p> |
