摘　　要：针对某随动稳定系统在调试过程中出现的失稳现象,设计了xPC环境下的CAN总线驱动模块,构建了基于xPC的实时仿真系统。对随动稳定系统的陀螺输出信号进行实时测试和记录。针对实测陀螺信号的非平稳特性,使用S函数完成小波去噪算法建模,设计了实时仿真控制系统的Simulink模型,对实测陀螺信号进行了实时小波去噪仿真分析。工程实践表明,实时小波算法对陀螺速率信号具有良好的去噪效果,该方法对随动稳定系统的调试和设计起到重要作用。Aiming at the phenomenon that the servo stabilizing system was unable to be stabilized when working, the CAN bus driving model was designed, and the simulation system platform based on xPC is designed. The gyro signal of the servo stabilizing system was tested and logged in real time. For the insta- tionariness of the gyro signal, S function is used to model the wavelet method, and the Simulink model of the real-time simulation system was constructed to simulate and analyze the logged gyro signal. Engineer- ing practice shows that the real-time wavelet denoising methods has a good effect on the gyro velocity sig- nal and takes an important role in the design and debug process of the servo stabilizing system.
