Helmholtz coils . . . - Electronics Forum (Circuits, Projects and . . . Now measuring with a magnetometer of a cell phone gives me a more or less 50% real value compared to the calculated theoretical value Measured with tw different phones You can also see that the substraction (changin the polarity of the input voltage) of the geomagnetic field gives me plus minus the same value
controller for magnetorquers | Electronics Forum (Circuits, Projects . . . I realize the control law will be in the form as T(toqrue) = M(torquer dipole moment) x B(earths magnetic field) and M = NIA, therefore T = MxBy - MyBx, where Mx is the dipole moment of the x-axis torquer and Bx is the x-component of the earths magnetic field I am using a magnetometer as the sensing device for angular position
Increasing data update rate of MPU9250 | Electronics Forum (Circuits . . . The MPU has magnetometer, acceleromter, gyro, and sensor fused readings If the compass has no trouble keeping up with a more reasonable turn rate, you might be saturating the gyro and many gyros give false readings when that happens (the output doesn't just saturate at the max angular velocity
How to test electric power steering (EPS) for stability on adverse road . . . Please consider commercial vehicle equipped with EPS ECU and other ECUs such as Antilock brake system (ABS), engine, transmission, Body Control Module (BCM), etc I would like to come up with tests for testing EPS on adverse road conditions such as wet or icy pavement for vehicle stability
Using MAGMASTER to get compass calibration settings. Hi, I use AK8963C Compass chips, for projects These each need calibration values, that are used in programs I asked a similar question quite a while back, and didn't realise that the answers I followed led me in a the wrong direction The previous results gave me a way of calculating a
