摘　　要：传统并联驱动技术以其功率密度大,成本低、可热切换等优点被广泛应用于热备冗余驱动系统,但其存在主从结构不利于容错的问题,为解决这一问题本文提出一种基于令牌总线的推举主机热备份冗余驱动策略。本文分析了传统并联驱动系统的主从结构特点后,将适用于分布式拓扑结构的令牌环总线技术与并联驱动技术相结合,解决了主从结构中主站宕机会引发整个系统宕机的问题。同时本文还探究了低环流并联驱动技术在推举主热备份冗余驱动系统中的应用情况。与传统方案相比,本方案提高了热备份冗余驱动系统的可靠性且降低了其运行环流。最后在Matlab环境中建立仿真模型,实验结果表明该方案可在不损失电机控制效果的前提下提高系统稳定性且有效控制驱动环流。Traditional parallel drive technology is widely used in hot backup redundant drive system for its advantages of high power density,low cost and hot swap.However,it has the problem that the master-slave structure is not conducive to fault tolerance.To solve this problem,this paper proposed a redundant drive strategy based on token bus for push host hot backup.After analyzing the characteristics of the traditional parallel drive system,this paper combined the token ring bus technology which was suitable for distributed topology with the parallel drive technology to solve the problem that the whole system breaks down when the master station breaks down in the master-slave structure.At the same time,the application of the low circulation parallel drive technology in the drive system of the main thermal backup redundant machine was also discussed.Compared with the traditional scheme,this scheme improved the high reliability of the thermal backup redundant drive system and reduces its operating circulation.Finally,a simulation model was established in Matlab environment.The experimental results show that this scheme can improve the system stability and effectively control the driving circulation without losing the motor control effect.
