AbstractInput time delay systems have many applications in the industry The delay in input maybe caused by communication signals command signals or an intrinsic characteristic of asystem So it is important to offer some methods for the control of input delay systems The main problem in the stability of input delay systems is the existence of time lag insystem input This prevents using input in real time Therefore it is necessary to solve thisproblem to have a reliable controller There are many suggestions for solving this problem One suggestion is to derive a prediction model which forecasts the system states Thismodel should compensate for the input time lag One such model is known as Artstienmodel which is used by many designers Artstien model however has no feedback fromthe system and is based on its time domain solution There are some examples that showthe stability of the closed loop system can not be achieved by this method In this thesis anew prediction model is presented for input time delay systems This model is based onobserver structure introduced in modern control It is proved that the prediction errorconverges to zero asymptotically The existance of feedback in the proposed model is oneof its advantages This model is derived for different linear input delay systems Acontroller is also designed based on this model and the closed loop system stability isproved for each case
