Raw bias magnetic field.Since electromagnet inductance coefficent is the function of guide rod displacement, the load of PWM is extracted from control electromagnet
It include guide rod displacement information in wave voltage (or electric current) ingredient.Since control electric current removes biasing in control voltage (electric current)
Outside the carrier component for the PWM that coil mutual inductance comes, there are also control electric current control electromagnet coil on generate voltage (including from
Electrification pressure).Therefore, controlling the resonance circuit 11a extraction that the voltage exported on electromagnet coil has to pass through detection system has
The PWM carrier signal of displacement information.By the signal of extraction after full-wave rectifying circuit 12a rectification, by low-pass filter circuit 5a-
2 become the low frequency signal containing guide rod displacement information.Control signal is converted to by controller again, through power amplifier 8a-2
Drive control electromagnet after amplification carries out closed-loop control to guide rod position.The controller 6a-2 of the present embodiment uses PID control
Device.
In the present embodiment, sensor is not used, using pulse-width signal as test signal, is extracted from test signal
Displacement information realizes guide rod self-centering in guide sleeve.
Embodiment 3:
In the present embodiment, sensor is housed, the position using sensor detection guide rod relative to guide sleeve on guide sleeve
It moves, realizes guide rod self-centering in guide sleeve.
Fig. 5 is guide rod eccentricity self-check system schematic diagram.Electricity routing sensor 14a, controller 6a-3, power are put
Two 8a-4 of big one 8a-3 of device and power amplifier, displacement conversion circuit 13a composition.
When guide rod bias, sensor 14a detects displacement signal after displacement conversion circuit 13a conversion, through controlling
Device 6a-3 and power amplifier 8a-3 is transformed to control electric current, and the electromagnetic force of regulating magnet keeps guide sleeve automatic with guide rod
Centering.
If use while using permanent magnet and electromagnet in above-described embodiment, the iron core of electromagnet can use E sections
The heart.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
