Abstract

PURPOSE:To hold stability by changing the speed of an actuator properly with the sum signal of a manual speed control signal and arithmetic speed control signal when correcting track control manually in automatic operation. CONSTITUTION:When switch 6' is closed on arrival of interruption signal (t) at switch 6' in automatic operation to connect adders 5 and 14 together, operating input equipment 2 generates interruption signal S to open switch 13. Input signal (w) to adder 5 is therefore cut off and output v'=k1v of input signal (v) to operator 15 is supplied to adder 14. Manual speed control signal (x) outputted from input equipment 2 is supplied to operator 16 to obtain x'=k2x, which is inputted to the other terminal of adder 14. Consequently, output (u) of adder 14 is the sum signal of signals v' and x' and the flow rate that corresponds to output (u) is outputted from flow-rate control mechanism 10 to hold a stable state.
