Abstract


In actual industrial production, many systems contain delay, such as chemical systems, lossless transmission systems, turbo jets, nuclear reactors, and is now the most popular network control systems. The time delays are due to change of the system state equations, so the delay be charged to system instability and performance deterioration of the main. Therefore, the delay system stability control theory has been a hot research topic. In addition, in practical engineering applications, due to the external environment and internal impact of technology, it is difficult to get an accurate mathematical model of the controlled system. In the control system design process models are often used to some extent in the linearization approximation obtained through the mathematical model. The resulting model and the actual characteristics of the object there is always a gap, in a sense, this gap can be seen as the system model uncertainty. This uncertainty is measured and can give a certain size constraints, such as parameter uncertainties with bounded polynomial nature or having a convex constraints. Then we can use the robust control theory to deal effectively with the system this uncertainty. Based on Lyapunov stability theory and linear matrix inequality approach, the introduction of the right to freedom of the matrix to represent the relationship between the system for a class of norm-bounded uncertain parameters, with both state and input delays of time-varying delay systems, the use of three types of feedback controller, ie memoryless state feedback controller and static output feedback controllers and dynamic output feedback controllers, stability and robustness of the system robust stabilization controller is designed to obtain a delay dependent stability criterion. Text consists of the following five chapters: the first chapter introduces the research background, the research status uncertain time-delay systems, robust control theory Overview and delay systems research profiles, as well as the contents of this paper, purpose and significance. The second chapter gives the paper the basic knowledge, basic theorems and related lemma. The third chapter discusses a class of state delay and control of linear time-varying input delay delay systems asymptotic stability of the system is given delay-dependent stability criterion and three feedback controller design methods, and the simulation results. Chapter IV discussed in the previous chapter added to the system uncertainties discussed a class of state delay and control input delays uncertain time-varying delay systems robust stabilization problem, given the system delay Dependent Robust Stabilization for a sufficient condition to obtain a three feedback controller design method, and through two numerical examples verify the correctness and validity of the results. Chapter V of this paper summarizes the results and outlook.
