故障检测与识别-滤波器研究
Fault Detection and Identification - a Filter Investigation
摘要:
本文基于解析余度的概念,提出了一种新的主动容错控制系统。新的设计包括一个基于观测滤波器的故障检测和识别系统集成的非线性模型预测控制器。设计了多个观测滤波器,将其与非线性控制器集成并在达到最终设计之前进行测试,该最终设计包括用于故障检测和识别的无迹卡尔曼滤波器以及非线性模型预测控制器,以形成主动容错控制系统设计。
英文摘要:
This paper develops a new active fault tolerant control system based on the concept of analytical redundancy. The novel design consists of an observation filter based fault detection and identification system integrated with a nonlinear model predictive controller. A number of observation filters were designed, integrated with the nonlinear controller and tested before reaching the final design which comprises an unscented Kalman filter for fault detection and identification together with a nonlinear model predictive controller to form an active fault tolerant control system design.
