2 IEEE TRANSACTIONSON INDUSTRIAL ELECTRONICS,VOL. 40, NO. 1, FEBRUARY 1993 Variable Structure Control: A Survey John Y. Hung, Member, IEEE, Weibing Gao, SeniorMember, IEEE, and James C. Hung, Fellow, IEEE Abstract-A tutorial account of variable structure control with brief discussions about its historical development are pre- sliding mode is presented in this paper. The purpose is to sented. introduce in a concise manner the fundamental theory, main results, and practical applications of this powerful control sys- A. The Basic Notion of VSC tem design approach. This approach is particularly attractive The basic idea of VSC was originally illustrated by a for the control of nonlinear systems. Prominent characteristics such as invariance, robustness, order reduction, and control second-order system [431, [ 1541 similar to the following chattering are discussed in detail. Methods for coping with X=y chattering are presented. Both linear and nonlinear systems are considered. Future research areas are suggested and an exten- +U 2y -x y = (la) sive list of references is included.

...repetition controlstructure?
Repetition controlstructure is also known as looping or iteration controlstructure. .Repetition is the act of repeating steps in a certain process. It consists of a branching backwards away from the normal sequence of steps towards an earlier step. The branching decision is based on a relationship between the values of known data (condition) at the time that the branching...

In the following example, the second line of the table specifies that tax due on a salary of $2,000.00 is $225.00 plus 16% of excess salary over $1,500.00 (that is, 16% of $500.00). Therefore, the total tax is $225.00 + $80.00, or $305.00.

Adopting the appropriate organization structures to effective strategy implementation is very important to the company’s development.
Companies change their structures to align with new strategic directions and competition and also to respond to development in their operating environment,like Samsung for...

...variable
The variable is the important aspects of the research. In research the concept are measure from variable. Variable are anythings that can take on differing or varing values. it mean that the value of variable vary from person to person, time to time or place to place but the meaning of variable are same to all. Thus variable are the charactestics of person, groups, objects, ideas,...
