Digital fast startup procedure for micro-machined vibratory gyroscopes using optimized fuzzy control strategy
In this paper, we present an optimized digital fuzzy control strategy in order to realize fast startup of MEMS gyroscopes in various ambient temperatures. In the proposed procedure, the MEMS (Micro-ElectroMechanical Systems) vibratory gyroscope is driven with a sinusoidal wave synthesizer of adjustable frequency based on CORDIC algorithm. The drive frequency is fixed on the resonant frequency of the gyroscope with a frequency controller. By deliberate design of startup frequency controller using fuzzy control strategy, the startup time is decreased effectively in different ambient temperatures verified with test results. A series of startup test is performed under ambient temperatures ranging from -30 to 60°C, the tested startup time is improved from ~2.5s (tested with PID frequency controller) to ~100ms. What's more, this procedure has a higher SNR of 88dB.
