参数辨识在陀螺仪性能分析中的应用
Performance analysis of gyroscope using parameter identification
摘要
Abstract
The paper presented a performance analysis method for flexible gyroscope. This method was based on the key performance indicators and the dynamic model of flexible gyroscope and it was applied in the following steps. Firstly, multisine, which was also called pseudorandom noise, was chosen as the excitation signal. With the excitation signal and response signal, and applying special algorithm, the preliminary discrete model could be obtained. Secondly,converted this discrete model to a continuous model using zero-order-hold method, and applied Gauss-Newton minimization method to refine the initial estimation to get the optimal model. The experimental results indicates that the fitness degree increases to 95. 3% and the residual error is in the tolerance band. The proposition, which is illustrated with practical results, provides a feasible technical measure and a theoretical basis.关键词
