Abstract: PURPOSE:To reduce a dead zone in the flow control valve of a continuously variable transmission, etc., by performing control by the sum of a first operating quantity for a controlled object position and a target position by means of an electronic control device and a second operating quantity by the function of a deviation quantity. CONSTITUTION:The deviation epsilon between the piston position X of a controlled object (flow control valve) 20 which is detected by a position detecting means and a target position XD is inputted into an electronic control device 18, to calculate a first operating quantity U1 which is determined by a defined control algorithm by a control means 18c. And, by adding a NULL valve and further adding the second operating quantity U2 of a triangular wave amplitude corresponding to the deviation epsilon by a triangular wave generating circuit 18b, the first operating quantity U1 is inputted into a PWM circuit 18f. Hence, it is subjected to a pulse width modulation and becomes an operating quantity U to control the position of the controlled object 20. This second operating quantity U2 is made its original amplitude when the deviation epsilonis small, i.e., in the vicinity of a dead zone while making judder small or zero when the deviation is large. Thereby, the dead zone of the flow control valve can be reduced while enabling smooth control over the whole controlling zone.
