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 a calculation method, system, electronic equipment and storage medium of an effective commissioning rate. The method includes: collecting data information of an MPC controller; The current value of the variable, the operating upper limit and lower limit of the manipulated variable, calculate the effective operating rate of the manipulated variable; use the MPC controller to use the switch state, the controlled variable to use the switch state, the current value of the controlled variable, and the operating upper limit of the controlled variable and the lower limit, calculate the effective commissioning rate of the controlled variable; calculate the average effective commissioning rate of all manipulated variables of the MPC controller and the average effective commissioning rate of all controlled variables; calculate the average effective commissioning rate of all manipulated variables of the MPC controller The average of the operating rate and the average effective operating rate of all controlled variables is used to obtain the effective operating rate of the MPC controller. Only a small part of the basic operating information of the MPC controller existing on the DCS can be used to calculate the effective commissioning rate.
