Abstract:
A servo control apparatus including a speed controller for controlling a servo motor so that a difference between a speed command signal and a speed feedback signal becomes a zero, wherein the speed controller has an infinite impulse response filter with characteristics adjusted in accordance with:Gf(s)=&ohgr;12(s2+2&xgr;2&ohgr;2s+&ohgr;22)/&ohgr;22(s2+2&xgr;1&ohgr;1s+&ohgr;12) wherein &ohgr;1, and &ohgr;2 are values close to the anti-resonance and the resonance frequencies, respectively, and &xgr;1 and &xgr;2 are set in response to anti-resonance and resonance peak amplitudes, respectively.
