Design of global sliding-mode variable structure model-following multi-variable control system

To solve unfavorable effects of parameter perturbation and external noise on the transient performance and robustness of tracking error, the global slide-mode modal-following multivariable control system was proposed. The designs of sliding-mode parameter matrix, sliding mode translational parameter and variable structure control law were presented. The simulation result has shown that the proposed design scheme is feasible, which could ensure effective tracking of the control object with the reference model.
