摘　　要：为满足全系统数字化需求,并确保产品可靠性,对各类三余度控制技术进行了对比分析。针对机械反馈式伺服机构的控制特点,对故障模式采用智能识别技术,分析了不同故障模式对伺服系统的影响。采用软硬件结合的智能控制技术,设计了一种新型三余度伺服控制方法;搭建了系统故障模拟试验平台,经验证满足设计意图,在一度故障及一种两度故障模式下,伺服机构性能也可以满足任务需求;最后对三余度伺服控制方法的发展进行了展望。In order to meet the requirements of the whole digital system and ensure the reliability of products,several technologies of three redundant control are comparatively analyzed,according to the characteristics of mechanical feedback servo mechanism,by using intelligent technology to identify failure mode,and the influence of different failure modes is analyzed for the servo system,the intelligent control technology of hardware and software combination is adopted,and a new type of triple redundancy servo control method is designed. By building the system fault simulation test platform,the result meets the design intent,when there is a fault mode,the performance of the servo system can meet the requirements of the task. Finally,the development prospect of the three redundant servo control method is discussed.
