Abstract

In this research the values of rejected and accepted (programmed) are compared to the variable control systems (VCS) by drawing curves and determine the values of the voltage switching surface system (VSS), which is working under the external effects and connect in the parts of control structure (S1, S2).The analysis presented here in treating the question of changing the structure when a deterministic disturbance acts anywhere in the control system using (Mat lab programs).
An adaptive model reference algorithm in established to make the control system respond satisfactory or not there is a disturbance. In this system best responses are achieve by noting many information and factors like steady state error (S.S.E), order of control system, type of switching and also notes the logarithmic structure for VSS voltages in case of input reference sources model to get best performance.
