PURPOSE:To improve responsiveness and the accuracy of control by providing a controller automatically adjusting a limit value in response to the condition of the mechanism to be controlled and changing the limit value in the high speed range and the low speed range of a generator. CONSTITUTION:A subtractor 21 in a scooper tube control apparatus 19 outputs a speed deviation signal S7 obtained from a scooper tube position setting signal S4 and a speed feed back signal S6. The output signal S7 is input into a sooper tube position control operator 23 through a signal limiter 22. Also, the scooper tube position command signal S5 output from the scooper tube position control operator 23 drives a scooper tube of a fluid coupling 15. Consequently, a scooper tube position signal S11 changes and the changed signal is fed back to a subtractor 21 through a scooper tube position detector 25 and also given to the speed limiter 22 through a speed detector 24. The limit value of the speed limiter 22 is low in the high speed range of a AC generator 16 and high in its low speed range. |
