Optimal Digital Control System of Drying Apparatus

Abstract

This article discusses the questions of selecting the quantization period of continuous control system, it determines the qualityof control system. The task of optimal control is assigned for drying apparatus, which is decided by means of discrete optimal stateobserver. Mathematical model and structural scheme of the digital double-channel system for drying apparatus are worked out.Stability margin of system is estimated by magnitude of oscillating quality. The quality indices of double channel automaticcontrol system (ACS) with optimal discrete regulator for the various quantization periods are given in table 1 and they are plottedcorresponding to transient characteristics.
