为了减小由于传感器带宽不足引起的系统的动态误差,采用时滞滤波理论设计动态补偿系统。将时滞滤波器的时域表达式具体化,并分析了其频域特性。基于已建模的传感器系统用矢量图法设计了补偿时滞滤波器,并在matlab中做了仿真,分析了补偿前后系统特性在时域和频域中的变化。提出一种实时实现时滞滤波器的方法。工程实验表明将时滞滤波器引入测试系统可以减小动态误差。
In order to reduce the dynamic error of the system caused by the lack of sensor bandwidth, the dynamic compensation system is designed by using the time-delay filtering theory. The time domain expression of time delay filter is embodied and its frequency domain characteristics are analyzed. The compensated time delay filter is designed based on the modeled vector system with the vector diagram, and the simulation is done in matlab. The changes of the system characteristics before and after compensation in the time domain and the frequency domain are analyzed. A real-time realization of the delay filter method. Engineering experiments show that the introduction of delay filters into the test system can reduce the dynamic error.
