Robust holographic control of complex interconnected systems with similar structure

Yan, Xinggang (1996) Robust holographic control of complex interconnected systems with similar structure. Doctor of Engineering (EngDoc) thesis, Northeastern University.


With development of scientific technology, the scale of engineering systems is more and more large. It is required that people must deal with some complicated systems and finish complicated tasks under complicated surroundings. Theorefore, we must face complicated systems seriously.

The paper may be summarized as follows:

In the second chapter, state feedback centralized controllers with holographic structure are designed for some similar systems such as nonlinear time-varying composite systems, nonlinear uncertain composite systems with isolated subsystems which are singal input linear systems or input-state decoupling systems, and parametric matched uncertain composite systems with isolated systems possessing uniform relative degrees. Then, state feedback decentralized controllers with holographic structure are designed for nonlinear similar large-scale systems with unmatched uncertainties. Because the controllers designed in this chapter are similar to"Bang-Bang"control and of holographic structure, it is easy to be designed in practical engineering systems.

In chapter 4, observer-based stabilization for nonlinear similar composite systems is discussed. The obtained results are applied to disc-shift systems. Simulation shows that the resuts are effective.

In chapter 6, some tracking problems are considered. A kind of iterative learning control problem is studied for a class of nonlinear similar composite systems in section 1, and robust variable structure controller is proposed for a class of similar large scale systems with matched uncertainties to track desired output in section 2.

Some problems to be investigated late and good prospects of the study of similar systems are proposed to conclude the paper.
