| Abstract: | The conventional AC servo system has many drawbacks, such as the complicated structure and the performance significantly influenced by various uncertainties, etc. To overcome these, a novel model algorithmic combined with variable structure control is proposed. A first-order ARMA model of the servo system is used as the parameter-model in the predicative control. To overcome various uncertainties, control is acquired by variable structure theories, and feedback tuning in real time on-line. Experimental results verify that the system exhibits good static and dynamic performance and isn' t influenced by various uncertainties. |
