Aided Tracking In Digital Filtering

To improve the trace precision of the servo system in some tracking set, the text adopts the computer aided control techniques based on digital forecast and filter. It particularly introduces the principle and application in the projection of the digital forecast and filter in this paper. Firstly, counterchanges the control signal coordinate, behind, forecasts and filters the waves according to the α-β-γ filter arithmetic, finally, reverts the forecasting result coordinate, and inputs the forecasting result to the servo system.The text particularly recites the academic gist of α-β-γfilter along with the practice in the projection. According to the practice instance, the filter adopts complicated coordinate conversion. Because it influences the last trace precision, the reason and method of the coordinate conversion is introduced in this paper. The flow chart of the filter course is presented also in the last, besides, we validate the upgrade of the system precision via the specialties experimentation.
