The stochastic systems are extremely common in industrial control areas such as, satellite attitude control, missile guidance control, and it also generally used in many domains, for example, transportation engineering, metallurgy, finance, and biotechnology. Moreover, the distributed delays widely exist in these fields such as, space flight, network control and signal communication. At present, the

Uncertain time-delay system has long been one of the international poplar research fields. One of its main is that, actually, most of the control systems are inevitably influenced by varies kinds of uncertainties, which come from the system itself and external disturbance. At the same time, time delaying and arbitrariness are also widely found in

The filtering problem is one of producing an estimate of the system state usingmeasurements, while robust filtering is to estimate an unknown hidden state whenthe system model exists uncertainty. This dissertation is concerned with the problemof robust filter design for a class of convex polyhedron uncertain systems, includ-ing linear systems, time-delay systems, multi-dimensional systems, and

The real plants not only contain nonlinearity, but also inevitably contain system uncertainty. Uncertainty may degrade system dynamic performance, even make the system unstable. So it is of great significance in both theory and applications to develop control strategy research to uncertain nonlinear systems.The good system dynamic performance can be obtained by using optimal control

The impulsive system is a class of hybrid system, it is composed by continuous dy-namic and discrete dynamic which effect each other. It is hot issues of control field. The study of the properties and synthesis of impulsive models has been developed rapidly for years. This paper mainly discusses the stability problem of normal linear

Nonlinearities and uncertainties are general for real models. Linear quadratic performance index can synthetically manifest the requirement of the system performance. The optimal control theory based on Linear Quadratic Regular (LQR) for linear systems has developed well, and achieved significant results. But it is difficult to get the analytical solutions, when it is used to

Based on the linear matrix inequality (LMI) method, Lyapunov stability theory and technique of inequality transformations, the guaranteed cost control problems are investigated for uncertain large-scale interconnected systems, uncertain time-delay systems, uncertain singular time-delay systems and uncertain singular time-delay markovian jumping systems. The main contents of this dissertation are written as follows:(1) The optimal guaranteed

There are inevitable time delays in a large number of natural and social phenomena. Namely, the development trend of things not only depends on the current state, but also relies on the past of things. The control of time delay systems is an important field of control theory. Time delay cause deterioration of system, and

With the rapid development of science and technology, the modern control system is large-scale, complicated, and automation degree is also higher. Especially in the high-tech fields, such as aerospace industry, robots, aircraft that make the accuracy of the control system face a higher challenge, and it is the urgent need that promote the rapid development
