英文摘要：

Based on the sampled-data system direct design study findings and faced upon practical problems that the sample period of the command input signal is much larger than the internal sample period of the simulation table control system, we study the mixed sensitivity design and the performance analysis for the special structure sampled-data control system, the table servo control system. By lifting the table control system, we propose the state space model of the lifted system and H∞ -norm equivalent discrete systems Subsequently, we discuss computational methods of the discrete controller. The analytic and design results indicate that the methods in this dissertation are feasible and effective.
