Translation of "Regelverstärkung" in English

The loop gain is then less, and the d.c. voltage converter is more stable against hunting.

The loop gain is then less, and the d.c. voltage converter is more stable against hunting.

A residual deviation according to the control gain remains.

Therefore the loop gain is improved with respect to conventional d.c. voltage converters.

In order to protect the output stage, the control gain is reduced, for example.

It is even possible to establish the variable-gain amplification while the device is playing.

The control gain setting is the same for both valves.

The invention concerns a method of and circuitry for automatically adjusting the variable-gain amplification in a control loop.

In such a case at least the signal connection is to be cut immediately downstream of the regulating amplification P 11 .

It will be appreciated that this can also be effected by the regulating amplification P 11 being set to zero.

Since a free oscillation build-up has to be avoided, the regular amplification is typically limited.

The DC signal at f=0 undergoes maximum control amplification and therefore maximum suppression.

To allow an adaptation to different controlled systems, it is equipped with an additional adjustable servo amplifier.

The stroke and control gain can be adjusted easily on-site by means of potenti ometer.

This simple two-position regulator with P control system is similar to the HT 22 model, but has no control amplifier.

Upon slight deviations between the frequency and/or phase of the reference signal and the second control signal the phase control circuit then shows a slight loop again, that is to say small deviations lead to only a small value for the reference phase signal.

Due to the more than proportional increase of the reference phase signal at the output of the distortion stage compared with the signal at its input upon relatively large deviations in the frequencies and/or phases of the reference signal and of the second control signal, however, the phase-locked loop achieves a high loop gain and hence a high control speed in the event of relatively large disturbances.

In a control circuit which only takes the gas flow into consideration, the main problem is that the resonateable gas column will have the tendency to overshoot the desired position given too large a controlled gain.

The process as in claim 1, further comprising analyzing the measuring signal from the measuring element at the output of the draw frame with the fuzzy controller to determine the response of the draw frame, and if necessary correcting the regulation onset point and regulation amplification through correction values generated by the fuzzy controller and inputted to the regulating system of the draw frame.

This continuous difference could be reduced by higher control amplification, which, however, can lead to a lack of stability, or by regulators having a special time behavior, which, however, are more difficult to optimalize.

In this manner, the control amplifiers controlling the X drive motor 14 may be operated with a higher control amplification, without causing the control circuit decaying into self-oscillation.

Any deviation is eliminated on the basis of a corresponding control of the modulation control voltage 10, except for a residual deviation that is dependent on the controlled gain of an evaluation circuit 6.

The actually levelled section can be further approximated to the desired section if the control unit has an adjustable control amplifier.

Using the difference between desired value and actual value multiplied by an adjustable control amplification V, the control unit 11 then determines an adjusting signal for an adjusting element 13 which is capable of adjusting the runout roller 5 in such a way that the location of the rolled section 1 is varied in the vertical direction.

The control amplification, which can be adjusted by means of these resistors RE3 and R11 among others, can also be adjusted by providing that the emitter surface areas of the transistors T13 and T14 are of different sizes, and in particular that the emitter surface area of the transistor T14 is a multiple of the emitter surface are of the transistor T13.

Although this effect may be attenuated by a reduction of the control amplification, this takes place at the expense of a sufficiently high control speed and thus of the control quality.

If the error continues to be present in an altered form in the output signal which is formed via scanning roller 4 and is transmitted via circuit 22 to the Fuzzy Controller 19, the Fuzzy Controller 19 can change the correction value of the regulation onset point (FIFO length) and/or of the regulation amplification as a function of position and form of the change.
