Abstract

The invention discloses a control method and device for a methanol-to-olefin reactor. Wherein, the control method of the methanol-to-olefins reactor includes: obtaining part of the operating variables among the plurality of operating variables used to control the methanol-to-olefins MTO reactor, wherein the part of the operating variables is selected from the plurality of operating variables according to preset rules The extracted variables that meet the predetermined conditions; determine the target variables used to control the MTO reactor according to part of the operating variables, wherein the MTO reactor works according to the target variables. The invention solves the technical problem of low reliability in the control of the methanol-to-olefins MTO reaction regeneration system in the related art.

Description

technical field [0001] The invention relates to the field of control science and engineering, in particular to a control method and device for a methanol-to-olefins reactor. Background technique [0002] The traditional methanol to olefin (Methanol To Olefin, referred to as MTO) reactor control system uses a conventional proportional-integral-derivative controller (Proportion Integration Differentiation, referred to as PID), and the PID controller adopts single-loop or cascade control as The main adjustment method is single-parameter adjustment, which is simple in principle, easy to use, strong in adaptability, and strong in robustness. Its control quality is not sensitive to changes in the controlled object. The PID controller is suitable for systems with good linearity and input not exceeding the slope. It is very simple and practical. However, it is very limited for complex nonlinear systems and load signal tracking. For systems with multiple inputs and multiple outputs,...
