Pointing and Tracking of Particle Beams.
Abstract
A problem is considered to determine the feasibility of using a Multiple Model Adaptive Estimator (MMAE) based on space-time point process observations, as part of a control loop. The estimator tracks the centroid of a one-dimensional Gaussian-shaped source of individual photo-electron events. The centroid is assumed to move dynamically as a first order Guass-Markov process. Estimator performance for two implementations (using 'best half' versus 'merge' rationale for limiting the number of individual filters in the MMAE structure) is described in terms of steady-state root mean square error evaluated as a function of six important system parameters. Estimates of the beam centroid are used by a regulator based on a Linear system and Quadratic cost criteria to determine the effectiveness of the method. For tracking purposes, a real-world target and a Kalman filter are provided based on a first order Guass-Markov process model, and the controller is tested in this environment. Results indicate that the estimator provides a viable means of controlling the position of the centroid. (Author)
