In target tracking, the measurements collected by sensors can be biased in some real scenarios, e.g., due to systematic error. To accurately estimate the target trajectory, it is essential that the measurement bias be identified in the first place. We investigate the iterative bias estimation process based on the expectation-maximization (EM) algorithm, for cases where sufficiently large numbers of measurements are at hand. With the assistance of extended Kalman filtering and smoothing, we derive two EM estimation processes to estimate the measurement bias which is formulated as a random variable in one state-space model and a constant value in another. More importantly, we theoretically derive the global convergence result of the EM-based measurement bias estimation and reveal the link between the two proposed EM estimation processes in the respective state-space models. It is found that the bias estimate in the second state-space model is more accurate and of less complexity. Furthermore, the EM-based iterative estimation converges faster in the second state-space model than in the first one. As a byproduct, the target trajectory can be simultaneously estimated with the measurement bias, after processing a batch of measurements. These results are confirmed by our simulations.

Planetary gearboxes operate usually in non-stationary conditions generated mainly by variable loadsIn order to understand the dynamic behavior of planetary gearboxes in such conditions, a mathematic modelinduces a variable speed of the transmission which is taken into account when characterizing the main dynamicThe computation of the dynamic response shows an intimate relation between the vibration amplitude levelobserved which is well characterized using Short Time Fourier transform more suited than the spectral analysis
Keywords: planetary gearbox non-stationary conditions variable load dynamic response time frequency analysis
