Abstract
Discrete
sliding mode control (DSCM) is one of the best techniques in
analyzing the dynamics of nonlinear systems. This paper
presents an improved discrete quasi-sliding mode control
strategy in which the control input for the next step is
determined by considering the dynamics of the current
disturbance, which improves the robustness of the system
dynamics with relatively smaller control effort. In fact,
the existing techniques fail to deliver satisfactory
response for parameter variations and time-varying external
disturbances, where as the complete robustness is guaranteed
in the proposed technique. This improved strategy is applied
to two different systems under various environmental
conditions and the results obtained demonstrate its
effectiveness and improved efficiency.
Keywords:
Variable-structure system, discrete time system, quasi
sliding-mode, state-space.
