Description

Technical Field

[0001] The present invention relates to the field of industrial control technology, and in particular to a method and device for generating an accelerated engineering fastest differentiator. Background Art

[0002] The Proportional-Integral-Derivative (PID) controller is an exponential control mechanism widely used in industrial process control, contributing significantly to the development of industrial productivity. From an observational perspective, the P action, I action, and D action (conventional differentiator) in PID represent the three basic observation mechanisms in feedback control: the current observation mechanism of the P action, the constant observation mechanism of the I action, and the lead observation mechanism of the D action. The specific method used to construct the I and D actions reveals that they are based on a first-order inertial filter (FOIF). The FOIF is a typical exponential tracking filter, so the I and D actions represent an exponential constant observer and an exponential lead observer, respectively. Therefore, PID control implements an exponential control mechanism.

[0003] The proportional-derivative controller (PD) plays a role of advance observation, and the performance of the differentiator directly determines the advance observation performance of the PD controller. However, existing conventional differentiators have the problem of poor differential performance. Summary of the Invention

[0106] Depend on Figure 8 It can be seen that the output of the accelerated engineering maximum proportional-differential controller AEFPD is significantly ahead of the proportional-differential controller PD, and the fluctuation amplitude of the output of AEFPD is significantly smaller than that of PD; compared with PD, the use of AEFPD has better leading observation performance for the first-stage superheated steam temperature process signal.
