ABSTRACT:
A proportional-integral circuit comprising a proportional element, an integrator and an adder. In an automatic mode, the proportional element delivers an output signal V.sub.P which is proportional to an input signal V.sub.i, the integrator delivers an output signal V.sub.I by integrating the input signal V.sub.i, and the adder delivers an output signal V.sub.PI which is the sum of the output V.sub.P of the proportional element and the output V.sub.I of the integrator. In a handling mode, the input signal V.sub.i is not applied to the integrator, and the output V.sub.P of the proportional element and an output V.sub.H of a manual handling source are applied to the integrator. A resistor is connected in parallel with a feedback capacitor in the integrator so that the integrator possesses an adding function. The adder adds up the output V.sub.P of the proportional element and the output V.sub.I of the integrator. Further, in this circuit, the gain of the integrator output V.sub.I relative to V.sub.P and V.sub.H is selected to be l
, and the gain of the adder output V.sub.PI relative to V.sub.I is selected to be n.
