[Conventional technology and its problems] Generally, the self-excited (") vibration type vibration device has the advantage of automatically tracking its resonance point, but some kind of control device is needed to maintain a certain limit amplitude. For example, when the saturation of a controller or a power amplifier is used to fix its amplitude, the output of the power amplifier becomes a rectangular wave and contains a large amount of high-frequency components. Iron is here. In Japan, Japanese Patent Application No. 6 1-1 54599 »The self-excited vibration type vibration device shown in circle 3 is shown. Circle 4 represents a square block that represents a part of the movement of circle 3 as a Fu Feng function. In Fig. 4, 1 represents the entire vibrating eaves, and its characteristic equation is shown as a circle. The amplitude detection detector 2 is close to the vibration machine 1 (for example, the proximity of the vibrating parts supply plaque is provided in a slip current sensor that combines its bovl (bovl) and the bottom spring), and its output In order to be supplied to the amplitude controller 3, the rotation of the amplitude controller 3 is supplied to the power amplifier 4. On the other hand, the output X of the vibration machine is supplied to the self-supporting vibration controller 7, but the negative feedback is provided by the adder 6. Since it is a self-excited vibration, its input is zero, and the addition of the adder 6 is supplied to The element 5 is extended once, and its round output is supplied to the power amplifier 4 described above. Vibration machine 1 vibrates by mass with acceleration dx2 / dt2, and with the extension of l / s (s is the Laplace transform, the same applies hereinafter). When the element is used, its velocity becomes dx / dt. The velocity multiplied by the viscous supply c becomes the vibrational damping force acting on the mass, and then the dx / dt is extended to the β element Ι / s to X, and multiplying it by the _ spring constant k becomes the complex element force quality·.

Although the vibration system is described in a comprehensive manner, the H system will be controlled as the control system is controlled, and sometimes the value is large. The difference is limited. The fixed line of the display shows that the value of η is straight. It is believed that the increase is greater than that of CJ @ 自 4 大振 导 ίΓ ι. The ΛΛ 41 device increases Κ0 so that the amplitude of the detection is large and the difference is large. However, if necessary, the essential part of the essential arteries has both large and large organs, and the powerful force IX Ρ amplitude is huge and it is increased to it. When the device is still large, the amplitude of the vibration is increased and the Γ is 100 to △ ai with a partial value of 0 ^ 0. The good frequency is beneficial to the high-frequency device. The large wave with an 8M shape is added to the vibration. The vibration is fffi2. 0 It ’s about to be released (please read the precautions on the back and then fill out this page) to install.

In addition, the above purpose is to use the vibration displacement detector that detects the vibration displacement of the vibration machine, and use the output of the vibration displacement detector as a negative feedback. The signal is amplified by feedback gain, and the integral vibration element or primary element is used to control the self-sustained vibration 1 controller of its phase extension, the output of the controller is amplified by a force amplifier, and the power amplifier receives the The vibration driver out of the amplifier, and the vibration vibration element is used to vibrate the self-excited vibration type vibration device of the vibration machine, so that the value of the feedback gain K is based on the amplitude of the time and the predetermined vibration The amplitude of the difference cadmium difference Δγ, with + △ r) 2N + l + KCr · (where Ki, Κν is a constant, H is an integer, Kcr is the gain of the stability limit) for the change of the self-excited vibration to be symbolized Type vibration device.

The period pseudo-change is formed by its self-supporting vibration type vibration device. [Function] Feedback gain K = ΚιΛ "+ ΚνΔ r2N + 1 + Kcr, and for example ΚιΔ r + K3 △ r3 + IUr is an odd number function, so when △ r is large, it is the third power standby, △ r 3 Because it is very large, the feedback gain K becomes larger and it is easy to cause self-excited vibration, and when the amplitude gong difference Δγ becomes small, it is abruptly small and becomes Kcr when the cadmium difference Δγ * is zero, and it becomes stable. The limit gain, whose vibration machinery is stable self-excited vibration, is held at a fixed amplitude. When the vibration speed of the vibration device is detected, it is also the same when the displacement is detected, and when the vibration is detected, the phase The body moves 90 degrees, so that the self-vibration bite occurs, and the vibration driver is the head magnet drive unit. When the vibration displacement is detected, the head magnet itself has a 90 degree phase extension. Therefore, the phase extension device is not required. The self-excited vibration is rapid and stable, and the vibration of the mine is held.

Circle 1 represents the self-supporting vibration type vibration device of the embodiment of the present invention, and the vibrating eaves in the figure The machine 11 in this embodiment is not limited to a vibrating part supply mole device but a The vibration driver 17 which supplies the vibration force to the vibration machine is not a high-magnetism type vibration mechanism and is cast as a pressure type or a dynamic type. Because this device is connected to its wheel-in terminal "There is no phase difference between the wheel output of the power amplifier 16 and the output (vibration force) of the vibrating mover 17. The detection part of the vibration speed detector 12 is a movable part mounted on the vibration machine U, or It is close to the configuration, or it is formed by the differential detector of the dynamic displacement detector, which is used by the Chinese paper rubbing rate (CNS) A4 specification (210X297 mm) (please read the back side first (Note ^ item, then fill out this page) Binding Rhenium A7 B7 Printed by the Central Sample Bureau of the Ministry of Economic Affairs Beigong Consumer Cooperative V.

The value of the present invention is as described above. The structure of the present invention is as described above »Secondly, its function is described. 0 1 1 The power amplifier 16 is connected to the DC 1 via a switch 1 when the source 9 is driven by the self-excited vibration of the vibration machine 11 »Close the two pairs and 1-wire to put the power amplifier in the operating state 0 Other self-excited vibration controller 15 , Amplitude-1 I The controller 14 and the like are also put into operation. In the amplitude controller 14, the amplitude of the movable part of the first vibration machine 11 is zero due to 1 1 1 • The amplitude anchor difference △ Γ 1 1 is the maximum 0, which is the initial value of the amplitude deviation △ r (target amplitude-«· zero ), 1 1 However, in the conventional case, as shown in Figure 4, it is shown in the straight line, that is, the DC amplification by the amplitude difference of 1 1 »or by the P ID amplification, with K = ΚρΔ γ of the feedback feedback gain 1 | Kc is a linear amplification. Therefore, the initial performance of the vibration of i is good. At the initial value of the amplitude deviation Δr of 1 I. The feedback gain K is the maximum value at this facility, but 1 1 I is such that If it is well-initiated, then it will grow bigger. As mentioned above, it will be superimposed on 1 1 paper scale. Applicable to China's national rate (CNS> A4 wash grid (210X297 mm). Install A7 B7 5. Description of the invention (8) The pulsation of the amplitude detector 13 is also amplified, so that the feedback gain K0 cannot be kept at a certain stable limit and will vary greatly. Therefore The output of the power amplifier 16 also changes. However, according to the present invention, the feedback gain K is supplied by the output of the non-linear calculation, and the factor that determines the feedback gain K at the initial value of the amplitude deviation Δγ is mainly the second term K3 in the above formula (Δγ ·) 3, so it starts to oscillate rapidly, and near the stability limit, the gain K that determines its amplitude is small, which can eliminate the small color pulsation W. Plaque 6 is the time that represents the feedback gain of the conventional case The change also means that the expansion circle of 900 ~ 91Bsee after the switch is put into operation, the gain K is a large change from the sinusoidal ring. On the one hand, FIG. 7 shows the time change of the feedback gain K according to the present invention. The stability limit gain of 900 ~ 910 «sec time is almost unchanged. This means that it is less affected by the pulsation of the vibrator 13. The above embodiment of the present invention has been described, but the present invention is not limited to this. The technical idea can be modified. For example, in the above embodiment, the vibration speed of the vibration machine 11 is detected, which is fed back to form a closed loop to generate a self-excited vibration, but instead of detecting the vibration speed, the vibration is detected. Displacement, the detected signal is negatively fed back to the self-sustained vibration mold controller 15, and its phase is delayed by changing the above-mentioned feedback gain K. The principle of self-sustained vibration can be understood that the vibration displacement is in the viscous vibration. There is a phase difference of κ / 2 with Lishen, and in order to extend the phase of * κ / 2, it is also possible to use a / 2 phase extension element. In addition, a vibration displacement detection device is used to vibrate When the driver is an electromagnet vibration mechanism, the mechanism will extend the phase by 890 degrees, so no need to use any -------- ^ 1 ^ ------ 1Τ ---- ^ --- ( Please read the precautions on the back before filling out this page) This paper scale is used in China National Standard (CNS) Α4 wash grid (210X297mm) A7 B7 5.
