基于特征提取的容错控制及其应用

Fault-Tolerant Control Based on Characteristic Extract and Its Application

在黄金分割鲁棒自适应控制器的基础上，设计了一种自适应被动容错控制器，能在线辨识对象特征模型，在线提取系统动态性能特征和故障特征，对控制系统执行机构和测量部件的某些软故障具有被动容错能力。与传统PID控制的对比仿真充分说明了这种控制方案的优越性。

Based on the golden - section robust adaptive controller, a passively adapivefault - tolerant controller is designed. The controller can identify characteristic model of aplant and on - line extract system dynamic performance and fault properties. So it is able topassively tolerate some soft faults of actuators and sensors of a control system. The advantagesof this controller have been showed by the simulation results compared with the PID controller.
