摘　　要：首先进行了压电陀螺漂移特性分析,重点研究了利用数字信号控制器(DSC,digital signal controller)和LabWindows/CVI软件设计出压电陀螺漂移测试实验,测量出压电陀螺实际的漂移误差数据,由此建立了压电陀螺漂移特性ARMA模型,设计出基于LMI的鲁棒滤波器,并与Kalman滤波器进行了仿真比较,提高了陀螺随机漂移的估计精度,保证了陀螺误差补偿的有效性。The drift performance analysis of piezoelectric gyroscope is introduced. The piezoelectric gyroscope drift test is mainly studied by means of digital signal controller（DSC） and LabWindows/CVI, and the drift error data is measured through this test. Then the drift characteristics ARMA model is identified. Based on this model, the corresponding robust filter is designed by means of the LMI-based robust filter method. Compared it with the Kalman filter through simulation, the proposed method improves the estimation accuracy of the gyro drift and guarantees the validity of error compensation.
