    • PURPOSE:To adjust the controlled variable of a control device of previous stage in accordance with the deviation between the controlled variable of a load controlling device of next stage and a set controlled variable so as to control a load stably, by introducing the deviation to a device which is used for an extruder, etc., for controlling load constantly. CONSTITUTION:Loading device of previous stage 5 and next stage 7 are installed to a load controlling device used for an extruder, etc., and thyristor devices 4 and 6 and speed setters 1 and 2 are connected to each device 5 and 7, respectively. Moreover, an ammeter 3 and current exchanger 9 are connected to the device 7. The quantity of an electric current flowing to the device 7 is detected by the ammeter and the controlled variable of the device 7 is converted into a voltage signal by the exchanger in accordance with the quantity of current. The controlled variable converted into the voltage signal by the exchanger 9 is compared with a value previously set at a load setter 8 at an operational amplifier 10 and an operational result is added to the thyristor device 4 and the speed of the device of previous stage 5 is controlled. In this way, the stability of the load is improved and highly accurate control is made possible.
