摘　　要：航空开关磁阻起动/发电一体化系统工作在电动状态和发电状态时控制率不同,但控制参数都为电流、导通角和关断角。针对一体化系统的特点,设计了一套模糊滑模变结构控制器。滑模变结构控制器将负载作为干扰项,通过对系统结构进行不断地调整,使得系统状态能够快速地达到滑模面并进行滑动模态运动,但系统存在抖振问题。针对滑模变结构的抖振问题,采用模糊控制对滑模变结构的趋近速度进行控制,使得在趋近速度和抖振问题上得到优化。仿真结果表明,在电动状态和发电状态下控制器能够很快达到稳定,并在负载状态突变和输入状态变化的情况下具有很好的鲁棒性。Although the control rate is different between electrical state and generation state in aviation switched reluctance starter/generator system,the control parameters are both current,conduction angle and turn-off angle. In view of integrated system characteristics,a fuzzy sliding mode variable structure controller was designed to make system state move to sliding mode surface quickly and move on it,however,chattering problems can exist. For the chattering of the siding mode structure,fuzzy control was used to control approach speed of the sliding mode structure to optimize the approach speed and chattering. The results of simulation show that the controller are steady soon in both electrical state and generation state,and it has good robustness in the case of load mutation and input state change.
