摘要
Abstract
An alternating disturbance magnetic field with two almost inverse directions is generated when electromagnetic actuator works. To eliminate the disturbance for roll angle detection system based on geomagnetic sensor, the direction with less strength disturbance was determined as that of the geomagnetic sensor, and the digital filter was adopted. A four-order IIR Butterworth lowpass filter was designed, the preload delay phase compensation method was proposed, and then the curve of preload phase was calculated. Experiment results show that the IIR Butterworth filter can effectively decrease the disturbance of geomagnetic sensor from electromagnetic actuator and the effect of delay phase was compensated by the preload phase, which guarantee that the roll angle detection system can work reliably and accurately.关键词
