Title: Correction input value generation method for precise track control of servo control system
Inventor: TAGAWA YASUYOSHI
IPC: G05B11/36
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To improve the delay of response of a servo control system, to prevent a decrease in diameter that is caused when two axes are simultaneously fed in a circular motion mode, and also to reduce the height of a projection that is produced in quadrant switching mode by correcting the deviation between the inverse transmission output and input in response to the correction deviation that is obtained via a low pass filter LPF. SOLUTION: A low-pass filter Q(s) eliminates a high frequency component that is caused by a transmission function H(s). The function H(s) having the faster responsiveness than a transmission function G(s) is set and its inverted transmission function 1/H(s) is multiplied by the output Y for obtaining the inverted transmission output 1. The difference d is calculated between the output 1 and the original input. The difference d' is zero when the inverse transmission function 1/G(s) of the function G(s) is multiplied by the output Y and the difference d' equivalent to the delay value of the function G(s) is calculated against the function H(s) when the function a/H(s) is multiplied by the output Y, and the difference d' is subtracted from the input for obtaining the correction input r' that can reduce the said delay.
