Iterative Learning Control Design With Open Scheme For Some Nonlinear Composite Affine Large-scale Systems

Reviewing the history of development of cybernetics, we can see obviously that control theory was coming from solving actual engineering or technology problems, and growing with them, just the same as other science. With the progress of control technology, complex control systems have been taken into more attention. More and more issues demand that cybernetics can deal with the more complex systems and provide more effective control strategy. However, the complex systems often have the characteristic of higher order, excessive loop, strict nonlinearity and interconnection, so it is difficult to design controllers for them by using a uniform and effective method.Recently, iterative learning control method usually is used to deal with the simple systems. Few methods are used in designing controllers for the composite large-scale systems. The special mathematic conditions, such as comparability, relativity, are proposed in some papers discussing large-scale systems. This restricts the application of the obtained results.By using open P-type, D-type and PID-type iterative learning control methods, this paper discusses the design of iterative learning controllers and proves the sufficient and necessary convergent conditions for a class of nonlinear composite affine large-scale systems. Finally, some examples show the validity of the methods adopted in this paper.Compare with other papers, the following figures are given in this paper:1) Every system model mentioned in the paper is needn't to presume satisfying comparability. So it is universality;2) In this paper, the tracking controllers are designed without the concept of relative degree;3) The assumptions in this paper are proper, so the corresponding results are adopted in the applications of the engineering;4) By using VB language, the software is constructed to simulate the dynamic control models for some systems.The paper is composed of five chapters. Chapter 1 is the simple introduction of iterative learning control. Chapter 2 discusses the open P-type learning method for a class of nonlinear composite affine large-scale systems. Chapter 3 discusses the open D-type learning method. Chapter 4 discusses the open PID-type learning method. Chapter 5 shows the simulation of...
