Abstract

PURPOSE: To ensure a positioning complied with the desired locus and over the entire process, by producting previously a kind of the voltage command curve for both the accelerating and retarding processes and then securing a ride-on of the half of the process onto the command curve for the accelerating process and then onto the command curve for the retarding process afte switching.
CONSTITUTION: The command velocity curve E(θ) is not based on the target stroke θ0 but on the accelerating process curve, and thus the F1(θ) is produced up to the angle of displacement θ=θn. And the retarding process curve is produced with the F2 covering from θ0-θ=0 through θ0-θm to be connected to the F1(θ). First, the angle of displacement θ is detected, and at the same time a calculation is given to θ0-θ. The E1(θ) is supplied according to the command curve at first. And in case the value of N (in the figure) produced from the feedback quantity of the detection velocity at θ=θP becomes equal to F2(θ0-θ), a jump is given from the point A to point B with a switching given to the F2(θ0-θ). And the E2(θ0-θ) is supplied at that moment. In such way, the command value can be switched not on the base of the value of the positioning target stroke θ0 but when reaching each design retarding curve corresponding to θ0. Thus a correct locus is secured toward the target value.
