Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] refer to Figure 1 to Figure 2 ,Such as Figure 1 to Figure 2 As shown, a method of overshoot suppression includes: sampling the system running step response trajectory, the speed inflection point in the rising stage of the step response curve; and then designing the input signal: first access the step signal, and then at the overshoot point, It is better to connect the anti-phase step response overshoot curve at the inflection point, and use it as an input to realize the actual effect of overshoot suppression and improve the stability of the system operation.

Abstract

The invention discloses an overshoot suppression method. The method comprises the following steps: sampling speed inflection points of a system operation step response trajectory and a step response curve in an ascending stage; and then designing an input signal: firstly accessing a step signal, and then accessing a curve of an anti-phase step response overshoot section at an overshoot point, preferably at an inflection point, so that the actual effect of overshoot suppression can be realized by taking the curve as an input, and the operation stability of the system is improved. According to the invention, the input trajectory is redesigned by utilizing the step response in an anti-phase manner. Namely, a reversed-phase curve of a step + step response overshoot section is adopted as input,so that overshoot suppression performance is realized; furthermore, an access time point is advanced to a speed inflection point to access the reverse-phase curve, overshoot is further reduced, and meanwhile it is guaranteed that the rapid performance is not reduced too much. And the actual effect of overshoot suppression is achieved.

Description

technical field [0001] The invention relates to overshoot suppression of a control system, in particular to an overshoot suppression method. Background technique [0002] At present, there are many methods of overshoot suppression in the control system. The traditional overshoot suppression methods include: (1) Select or improve the algorithm to improve the effect of overshoot suppression; (2) Based on advanced wavelet Analyzing the adaptive method of mutation signal detection technology; (3) Designing the input trajectory, using the smooth traction and braking target curve of the quadratic curve to improve the overshoot suppression effect; some analyzing using the PI speed regulator and using The overshoot suppressor does not affect the quickness and realizes no overshoot; (4) Use the data obtained from the closed-loop step response to perform the proportional coefficient, integral constant and differential constant of the PID controller for the control system whose model o...
