Abstract

PURPOSE:To avoid the undesired actions of the helm by preventing the increment of the amplification factor of the frequency band where the disturbance signal is high even though the amplification factor of the low frequency band may be increased. CONSTITUTION:The azimuth error signal is applied to the input terminal 14 and then applied to the plus input terminal of the amplifier V via the resistance R3. The amplifier 7 forms a voltage follower and is also connected to the proportion element amplifier P via the variable resistance R3. And the output of the amplifier P is connected to the input terminal of the amplifier V via the capacitor C1. Thus an LPF having the Miller effect can be obtained. And the output of the amplifier V is also applied to the differentiator D and the integrator I. As a result, the increment of the response velocity to a sudden change of the error signal plus the error occurrence due to the offset can be prevented. The outputs of these amplifier P, differentiator D and integrator I are applied to the error amplifier 5 to be converted in to the desired voltage. In such constitution, the amplification factor of the proportion factor amplifying part P' is reduced with increment of the resistance R3 for sensitivity adjustment and vice versa. Accordingly, the time constant of the LPF increases or reduces according to the amplification factor. AS a result, the amplification factor is never increased at the high frequency band even though the amplificatin factor may increase.
