Getting confused in IMU blook specifications.
Show older comments
In my real IMU sensor datasheet I have the following specifications in their attached units, but the required ones in the SIMULINK IMU block are quite different as follows:
in my dts: Angle Random Walk is 0.5 in (°/√hr) but the required one in the SIMULINK IMU block is in ((rad/s)/√Hz)
in my dts: Rate Noise Density is 0.033 in (°/sec/√Hz) but there is no such specification in SIMULINK IMU block.
In addition to the previous issue, SIMULINK IMU block requires the parameter called (Rate random walk in ((rad/s)*√Hz)), but on my datasheet I do not have scuch thing in the same unit as well as in the block, it requires sth called (Constant offset bias) but i do not have it on my datasheet.
What I literly have on my datasheet are:
Dynamic Range in (°/sec) -
Sensitivity x_GYRO_OUT and x_GYRO_LOW (32-bit) in (°/sec/LSB) -
Repeatability1 −40°C ≤ TC ≤ +85°C in (%) -
Sensitivity Temperature Coefficient −40°C ≤ TC ≤ +85°C, in (ppm/°C) -
Misalignment Axis to axis in (Degrees) -
Axis to frame (package) in (Degrees) -
Nonlinearity Best fit straight line, in ( %) of FS -
Bias Repeatability1, 2 −40°C ≤ TC ≤ +85°C, in (°/sec) -
In-Run Bias Stability in (°/hr) -
Angular Random Walk in (°/√hr) -
Bias Temperature Coefficient −40°C ≤ TC ≤ +85°C, in (°/sec/°C) -
Linear Acceleration Effect on Bias Any axis, in (°/sec/g) -
Output Noise (No filtering) in (°/sec rms) -
Rate Noise Density f = 10 Hz to 40 Hz, no filtering in (°/sec/√Hz rms) -
3 dB Bandwidth in (Hz) -
Sensor Resonant Frequency in (kHz)
I would like to simulate my IMU sensor upon these specifications.
I would be pleasure to help me implementing my real IMU and solving my issue.
