Motion-Scan Effect
The scanning process of lidar scanners is extended over time. Hence, relative motion between sensor and object during the scanning leads to a motion-dependent blur, here called motion-scan effect ...
Keywords: parameter estimation, lidar scanner, optimal estimation, identifiability, relativ motion
11/2006 | at – Automatisierungstechnik, Oldenbourg WissenschaftsverlagFast Algorithms for State and Parameter Estimation on Moving Horizons
We treat the problem of moving horizon state and parameter estimation (MHE) and propose a formulation for differential-algebraic systems that assumes a deterministic system behaviour on the estimation horizon, and which uses a regularization of the initial value...
Keywords: multiple shooting, parameter estimation, state estimation, nonlinear model predictive control, differential algebraic equations
12/2006 | at – Automatisierungstechnik, Oldenbourg WissenschaftsverlagFault Diagnosis for Hydraulic Servo Axes
This paper presents a model-based fault diagnosis system for linear hydraulic servo axes. Parity equations and parameter estimation methods are employed for fault detection, which are based on a precise physical model of the hydraulic plant...
Keywords: fault diagnosis, condition monitoring, hydraulic servo axis, parameter estimation, parity equation
