Abstract
The invention discloses a self-stabilization waveform generating method which comprises a waveform generator, an error adder and an error generator. By means of the self-stabilization waveform generating method, changing of waveforms, which is caused by load changing, can be automatically compensated, so that the purpose of self-stabilizing waveforms is achieved.
Description
Technical field
The invention belongs to the detection resources instrument field, relate in particular to a kind of self-stabilization waveform generation way.
Background technology
In the machine diagnostic system, must provide the benchmark of a kind of periodic voltage signal of standard as deformation and vibration measurement.But because the situations such as on-the-spot and load is changeable, usually so that the periodic voltage signal of this standard becomes unstable, cause the unstable of mechanical detection, accurately detect mechanical system, a kind of Waveform generation method of self-stabilization is necessary.
Summary of the invention
The object of the present invention is to provide a kind of self-stabilization waveform generation way.
The technical scheme that realizes above-mentioned purpose is: a kind of self-stabilization waveform generation way, it is characterized in that, and comprising: waveform generator, error adder and error maker, wherein:
Described waveform generator generates waveform Vs and exports to described error adder and error maker;
Described error adder generates waveform Vs with described waveform generator and is superimposed with the error Vf that described error maker generates, and forms output waveform Vout;
Described error maker generates waveform Vs with described waveform generator and deducts the output waveform Vout that described error adder generates, and forms error Vf.
Above-mentioned waveform generator generates waveform Vs arbitrarily periodic function waveform occurs.
The invention has the beneficial effects as follows: the present invention can auto-compensation because the change that the waveform that load variations causes occurs, reach the purpose of self-stabilization waveform.
Description of drawings
Fig. 1 is schematic flow sheet of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Please refer to Fig. 1, the present invention includes following steps:
A kind of self-stabilization waveform generation way is characterized in that, comprising: waveform generator AD835, and error adder AD620 and error maker AD8051, wherein:
AD835 generates waveform Vs and exports to AD620 and AD8051;
AD620 generates waveform Vs with AD835 and is superimposed with the error Vf that AD8051 generates, and forms output waveform Vout, obtains formula 1 and is expressed as follows:
Vout=Vs+Vf; Formula 1
AD8051 generates waveform Vs with AD835 and deducts the output waveform Vout that AD620 generates, and forms error Vf, obtains formula 2 and is expressed as follows:
Vf=Vs-Vout; Formula 2
Formula 2 substitution formula 1 obtain 2 Vout=2Vs.
Principle of the present invention is: the error auto compensatng of output waveform and reference waveform on output waveform, is obtained the reference waveform of stable output, reached the effect that the self-stabilization waveform occurs.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not consist of limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
