Abstract: PURPOSE:To reduce an error generated immediately after the step-like change of an objective acceleration of a controlled system slarply by changing the feedforward value of a servocontrol device adaptively like steps in accordance with the code of an error between the objective position of controlled system and a real position. CONSTITUTION:When an acceleration (a) is changed like steps as shown in Fig. (b) in accordance with a continuous trapezoidal speed curve in Fig. (a), the feedforward value (f) is linearly changed from f1 to f2 in an accelerating section from time t1 to t2 as shown in Fig. (c). The feedforward value is a fixed value fc is a constant speed section from the time t2 to t3 and the value (f) is linearly changed from f3 to f4 in the decelerating section from the time t3 to t4. Since large errors e1-e4 are generated immediately after the step-like change of the acceleration (a), the errors e1-e4 can be reduced by changing the f1-f4 properly in accordance with the code of the error ei at the time estimation of a continuous trapezoidal speed curve.
