| Abstract |
A microprocessor-based variable structure AC servo system with sliding mode is described, in which the boundary conditions for the existence of sliding mode is discussed and the problem of chattering is solved. In order to simplify the model of the controlled object, an inner vector controlled loop is adopted. A three step phase plane trajectory for sliding mode control is used to enhance the robustness of the system. Digital simulation and experimental results confirm that the dynamic performance of the system is insensitive to parameter variations and disturbances. |
