| 摘 要： | 针对复杂非线性系统被动容错控制问题,提出将AREs与小生境遗传算法相结合的方法。在T-S建模的基础上,这种方法用于搜寻最优控制器。在小生境遗传算法中提出了交叉变异概率的自适应调整律,克服遗传算法早熟的缺点。为了消除T-S建模误差,应用在线可调且具有补偿项的RBFN来消除建模误差。歼击机在多种故障下的仿真表明,此方法能够实现很好的容错控制效果。

| Abstract: | According to the problem of designing a passive fault-tolerance controller for the complicated non-linear system,a method is proposed which combines the AREs iterative algorithm and the niche genetic algorithm to search for the best controller based on the T-S modeling.The adaptive law of crossover ratio and mutation ratio is proposed to overcome the prematurity characteristics of traditional GA.To weaken the effect of modeling error,ARBFN is used,which can be adjusted on-line and has a compensation item.Simulation on the fighter aircraft under two serious actuator faults showed that it can obtain nice fault tolerant controlling effect. |
