Position Error Analysis for Dead Reckoning Algorithm Based on SINS/OD
Turntable errors, including
position error, wobble error, orthogonality error, and intersection error, will inevitably affect the GyroWheel system in calibration tests [11].
Lowest Bound on [beta] with Microphone
Position Errors. Denote the
position error of the mth microphone as [DELTA][r.sub.m]; that is, the actual position of the mth microphone is given by
(iv) In the process of broken line motion trajectory tracking,
position error is [P.sub.error2] = (-0.191 m ~ 0.183 m), the average residual rate is 8.9%, and confidence coefficient is 91.1%, as shown in Figure 27.
We denote the declared position of anchor node Na as [X'.sub.a] = [[[x'.sub.a], [y'.sub.a], [z'.sub.a]].sup.T] and describe the
position error vector [V.sub.a] = [[[v.sub.ax], [v.sub.ay], [v.sub.az]].sup.T] with standard multivariate Gaussian distribution.
As one can see, up to 200 ms (0, red line) oculomotor system is predicting trajectory of the occluded target; therefore a
position error does not increase.
Integration of noise results in bias, and the integration of bias results in a large linear
position error. To further complicate matters, linear accelerometers also measure gravity, and any error in angular position couples into the accurate removal of gravity and the linear
position error.
3, every different type of lines presents the values of
position error for the three joints.
* Servo loop compensation using a full 32-bit
position error, PID with velocity and acceleration feedforward, integration limit, and dual bi-quad filters.
This leads to significant
position error signal, or PES.
(4) The errors at the 12-h forecast point would be due to a combination of the initial
position error along with the first usable prediction errors.
A simple static acceleration error, known as an acceleration bias, will integrate to a linear velocity error, and a quadratic
position error. Bias is just one of many types of sensor error, and the analysis quickly gets considerably more complex with gyro rotation errors coupling to
position errors as well.
