A new sliding-mode control algorithm with simulation

A new design approach of the sliding-mode variable structure controller basing on the eigenvector of the specific area is presented for the position tracking servo control system in this paper. In order to accelerate the reaching phase and reduce chattering, the exponential approach law is adopted as the control function. Simulation results show that the new control algorithm exhibits the better control performance than the classical control method. Moreover, its realization is simple and convenient.
