hello,someone could help me to explain the follow figure phenomenon in the acceleration process ? (ADIS16488)
its acceleration output is not continous incresement.
ADIS16488 output abnormal!!
Thank you for the post. We will be glad to help. To start with, can you help us understand how we can eliminate the actual motion profile as the cause of such a response?
Thanks for your attention. Well,we have another MEMS-IMU(Inertial Measurement Unit) named STIM300.
We had used the two IMU measure the rotation motion of the dual axis test at the sametime.
Otherwise,we have three adis16488,they are all same response. We do not configure any register,even including the bandwidth.
I will post the response figure of stim300 tomorrow morning, because i had got off work hahahahaha....
Ok, sounds good. Also good to make sure that the frequency response and sample rates of the other solution we capture this type of motion.
I am terrible sorry,yesterday is too busy.
if there is something unclear in figure below,and something else you need to know ,please tell me.
Thank you! We have not seen this in our testing, so I would probably start looking for alternative ways to validate the communication link and data processing in your signal chain, in particular, the method you are using for combining the two data registers together.
With respect to your plot, I am not sure that I understand what your tying to measure. Based on 50 SPS, it would seem like the 0 to 10 dps/s rise takes 10 seconds. When combined with a delta of 10 dps/s, it would seem like the ramp time is 1 dps/s, not 10dps/s. Perhaps I should ask, what does the x-axis represent? The rate or acceleration rate of rotation?
Thank you .
Well.The the x-axis represent the acceleration rate of gravity.
Let me say something clearly.
First,the motion is The Dual Text table(figure below) rotates 90 degrees around the x-axis with 10 dps and 10 degree /s^2(Angular acceleration),like the Gyroscope output shows in figure below (red line).
you see,the gyroscope raw output is not normal yet.otherwise,the other Gyroscopes (y-axis and z-axis)and Accelerometers(x-axis and z-axis) have the same output forms if measure rotating motion.
the IMU Coordinate System is consistent with the Coordinate System of text table .
