摘要：
A robust filtering methodology is proposed that reliably preserves the information encapsulated in a process signal corrupted with noise and outliers. The method is proven to be effective on benchmark examples and implemented successfully in real-time on a pilot-scale distillation column. (C) 2001 Elsevier Science Ltd. All rights reserved.
