The invention provides a feedforward control system of an air separation equipment model, and is applied to the air separation equipment. The equipment comprises a detection module, a calculation module, a control module and a fine adjustment module, wherein the detection module is used for judging whether the air separation equipment needs to change a control mode or not, the calculation module is connected with the detection module, and is used for calculating parameters required by changing the control mode; and the control module is connected with the calculation module and used for controlling and adjusting the air separation equipment, and the fine adjustment module is connected with the control module and used for carrying out fine adjustment operation on the adjusted air separation equipment. According to the system and the method, under the condition of combining process simulation and multi-parameter control, a model feedforward control is carried out on the air separation equipment by utilizing an advanced algorithm, the equipment is automatically adjusted and runs on the designed optimum working condition all the time, and the effects of reducing the energy consumption and the automatic variable load are achieved while the personnel intervention is reduced.
Description
technical field [0001] The invention relates to air separation equipment, in particular to an air separation equipment model feedforward control system and method. Background technique [0002] In terms of the development of the MPC (Modeling Predictive Control, model feedforward control) system and the application of business modules, with the rapid development of large and extra-large air separation equipment, users of air separation equipment have higher and higher requirements for automatic control, especially for automatic control. Variable load requirements are getting higher and higher. Due to the large gas production of the device, once the load changes, if the product is vented, it will cause a lot of energy loss, so more and more users put forward the requirement of variable load control. In addition, because the air separation unit has the characteristics of complex process, serious coupling, and nonlinearity caused by large-scale variable loads, the manual varia...
