Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The accuracy analysis of simulation the analog automatic control systems Shilin A.N., Kostryukov K.E. This article deals with different methods of the analog automatic control systems’ simulation using a Z-quantic. The comparative analysis of these methods accuracy, which allows soundly choose the technique of a Z-quantic and parameters of the analog automatic control systems’ digital models, has been carried out.
