Abstract

The invention discloses a design method and device of an acceleration type engineering steepest controller, equipment and a medium, and the method comprises the steps: obtaining the process output of a transfer function in unit step input based on the transfer function of an acceleration type steepest tracking filter; according to the output characteristics of process output, generating an approximate acceleration steepest tracking filter by using a cascade pure lag link approximation method; a first-order inertial filter is adopted to replace a pure lag link in the approximate acceleration type steepest tracking filter, and an acceleration type engineering steepest tracking filter is generated; constructing an acceleration type engineering steepest integrator by using an acceleration type engineering steepest tracking filter; and constructing an acceleration type engineering steepest controller by using an acceleration type engineering steepest integrator. The first-order inertial filter is adopted to replace a pure lag link in an approximate acceleration type steepest tracking filter, engineering of the acceleration type steepest tracking filter is achieved, the finally obtained acceleration type engineering steepest controller is free of accumulative errors, and the control precision is higher.

Description

technical field [0001] The present application relates to the technical field of industrial process control, and in particular, to a design method, device, equipment and medium of an accelerated engineering fastest controller. Background technique [0002] The proportional-integral-derivative controller (Proportional-Integral-Derivative, PID) has been widely used in the field of industrial process control, promoting the formation of huge industrial productivity. However, the shortcomings of PID control are also obvious, for example, there are problems such as low dynamic control accuracy. [0003] At present, an engineering fastest tracking filter (EFTF) has been proposed in the prior art, which is essentially the engineering result of a (zero acceleration type) fastest tracking filter (FTF), the so-called fastest tracking, That is, the fastest track input or the minimum track input time. The so-called FTF engineering is an engineering method that approximates the FTF. Si...
