摘      要：The non-linearity problem of aircraft system could not be overcome by using the MEMS sensor *** order to improve the accuracy of aerial vehicle attitude,an aircraft attitude estimation of the MEMS sensor based on modified particle filter is *** aircraft attitude is optimized by the conjugate gradient method,and the drift error of gyroscope is ***,the particle weight is updated by the observed value to obtain an optimized state ***,the conjugate gradient method and the modified particle filter are weightily combined to determine the optimal weighting *** attitude estimation is carried out with STM32 and MEMS sensor as the core to design *** experimental results show that the static and dynamic attitude estimation performances of the aircraft are *** performances are well,the attitude data is relatively stable,and the tracking characteristics are ***,it has better robustness and stability.
