基于系统特征的自适应被动容错控制及其应用研究

ADAPTIVE PASSIVE FAULTTOLERANT CONTROL BASED ON SYSTEM CHARACTERISTIC EXTRACT AND ITS APPLICATION

本文在黄金分割鲁棒自适应控制器［１，２］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 adaptive faulttolerant controller is designed.The controller can identify characteristic model of a plant and online extract system dynamic performance and fault properties.So it is able to passively tolerate some soft faults of actuators and sensors of a control system.The advantages of this controller have been showed by the simulation results compared with the PID controller.
