英文摘要	This paper presents a method to accomplish automatic and real-time mode-matching control for a microelectromechanical systems vibratory gyroscope based on improved fuzzy algorithm and neural network algorithm. Meanwhile, robust control for the sense mode is applied to enhance the reliability of the closed-loop system. Experimental results demonstrate that it only needs similar to 8 s to achieve mode-matching intelligently in the improved fuzzy control system. In addition, a mismatching error <0.32 Hz is achieved over the temperature range from -40 degrees C to 80 degrees C in the neural network real-time control system, which is improved by more than one order of magnitude compared with that of once-time control system. In addition, the temperature coefficient of the zero bias is also improved to be 0.5 degrees/h/degrees C in the real-time mode-matching control system. Experimental results of phase margin, gain margin, and sensitivity margin indicate that the closed-loop system is stable and robust enough over the full temperature range. Moreover, the bandwidth and bias instability of the mode-matching gyroscope with closed-loop controlled sense mode are >85 Hz and <5 degrees/h, respectively.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000349114300011&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Electrical & Electronic; Instruments & Instrumentation; Physics, Applied; SCI(E); EI; 0; ARTICLE; hechunhua@pku.edu.cn; zqc@pku.edu.cn; 971230012@163.com; liudachuan@ime.pku.edu.cn; z.yang@pku.edu.cn; dchzhang@ime.pku.edu.cn; gzyan@pku.edu.cn; 4; 2069-2077; 15
