Robust periodic disturbance compensation via multirate control
A multirate discretization based adaptive feedforward compensation (AFC) scheme is proposed for repeatable runout (RRO) compensation in hard disk drive (HDD) digital servo systems. By discretizing the plant via multirate sampling, we can attain the inverse of the closed-loop transfer function no matter whether the closed-loop system is a minimum phase and causal system or not. The proposed scheme cancels selected RRO components rapidly without amplifying unselected higher harmonics. The scheme is applied to RRO compensation in a spin stand servo system. Simulation and experiment results show that the scheme can attenuate selected RRO harmonics effectively especially around 2 kHz which cannot be achieved by the conventional AFC scheme
