Problems solved by technology

[0009] The calculation of the effective commissioning rate of the model predictive control system in the prior art has some inherent defects: 1) the scope of application is limited, taking Aspen Watch as an example, it can only be applied to Aspen's own products, such as AspenDMCplus; 2) The calculation of the effective utilization rate requires the control system to provide a large amount of original information, including basic operating data and model relationships. However, because the existing model predictive control system provides original information through DCS, it often cannot meet the above requirements

Abstract

The invention provides an effective commissioning rate calculation method and system, electronic equipment and a storage medium. The method comprises the steps of collecting data information of an MPCcontroller; calculating the effective commissioning rate of the operation variable by utilizing the commissioning switch state of the MPC controller, the commissioning switch state of the operation variable, the current value of the operation variable and the operation upper limit and the operation lower limit of the operation variable; calculating the effective commissioning rate of the controlled variable by utilizing the commissioning switch state of the MPC controller, the commissioning switch state of the controlled variable, the current value of the controlled variable and the operationupper limit and the operation lower limit of the controlled variable; calculating the average effective use rate of all operation variables and the average effective use rate of all controlled variables of the MPC controller; and calculating the average value of the average effective use rate of all the operation variables of the MPC controller and the average value of the average effective use rate of all the controlled variables to obtain the effective use rate of the MPC controller. According to the invention, the effective commissioning rate can be calculated by only needing a small partof basic operation information of the MPC controller existing on the DCS.
