Variable Integral Digital Control Research of Pure Delay System

In order to eliminate the impact of delay on excessive process of system and improve system performance,a variable integral digital control of pure delay system was presented based on dynamic performance indicators.The basic idea was that step response of system was divided into 6 areas and control variables of controller were adjusted in real-time in different regions so as to achieve the overall optimal control effect.The control strategy and simulation control results were given.The method only needs setting two parameters and they had definitude physical meaning.Simulation results how that this control method have setting parameters simple,easy-to-use and have certain adaptive,etc.It can be obtain satisfaction control effect.
