## Matlab时滞系统的代数状态估计研究

Title  Study on the state estimation algebra for the first class of time delay systems
Abstract
Time-delay system refers to one or several signal transmission time delay system.Time lag phenomenon often becomes the root of the deterioration of system performance and even instability.Literature is the study of time-delay systems control and stability, this graduation design mainly studies a class of time-delay systems state estimation problem.
In understanding the stability of the time-delay systems, control method and state estimation methods of the status quo, problems and difficulties, on the basis of our algebraic state estimation method is designed for a class of time-delay systems, and provides the example simulation under Matlab simulation verify the feasibility of the algorithm.Calculation speed and high estimation precision, this method can not only estimate for time-delay systems (the practical application of a positive impact, can also for other types of system state estimation provides a new train of thought.
