معايير للتحكم والوصول في النظم الخطية المتقطعة

In this research many definitions and theories have been manifested regarding the specifications of controllability and accessibility in optimal control for discrete system of the type: X(t+1)=AX(t)+Bu(t+1) X(0)=Xo , |u(t)| 1 The following results have been reached : 1 - Transforming control system to the problem of linear programming. 2- Finding a series of new results of controllability and accessibility for optimal control discrete system. 3- Putting out a new algorithm to find the minimum number of steps that can enable us to move the state system from the primary stage into the final one. 4- Giving an example which shows the truthfulness of the previous algorithm .
