基于GPC的主动容错控制研究

Active Fault Tolerant Control Based on GPC

研究了一类含有一般故障的线性系统的故障检测方法和基于GPC(广义预测控制)的容错控制问题,提出了GPC容错控制律的设计算法.通过构造故障观测器在线检测系统故障和干扰,把估计的故障和干扰信息用于预测模型输出,得到了GPC容错控制律.仿真示例验证了故障检测方法和GPC容错控制律的有效性.

A new fault detection method for a class of linear systems with general failure and GPC（Generalized predictive control）-based fault tolerant control are studied,and a GPC fault tolerant control law is proposed.A fault observer is designed to detect failure and disturbance,and then these estimated information is used to predict the model output in order to obtain the fault tolerant control law.Simulation example shows the effectiveness of the fault detection scheme and the GPC fault tolerant control law.
