An estimator for reducing noise is disclosed. The estimator receives an input signal from controllably driven mechanical parts (the "plant"), estimates an internal physical quantity in the plant and outputs a first estimated physical quantity. A low frequency filter receives a detection signal from the plant. Another estimator receives the low frequency detection signal and outputs a second estimated physical quantity. A mixer receives the first and second estimated physical quantities and outputs a third estimated physical quantity.
