Nettet22. des. 2008 · Abstract: A new nonlinear compensation technique to capacitor pressure sensor (CPS) based on least square support vector regression (LSSVR) is proposed. … NettetThis paper proposes a linear compensator algorithm to improve the performance of an absolute multipolar magnetic encoder (AMPME). An AMPME is an absolute magnetic rotary encoder that uses a multipolar magnet (MPM) to increase the resolution. The resolution can be dramatically increased in proportion to the number of poles in the …
NettetSo an angle random walk specification of X ∘ / s is equivalent to a specification of ( 60 ⋅ X) ∘ / hr. Finally, the units used for specifying accelerometers often switch between the SI m/s/s and the more common milli-g (mg) (or even micro-g, μ g). It is useful to remember that 1 mg ≈ 0.01 m/s/s. So a noise density specification of X mg ...
