摘　　要：针对仿真转台在应用中存在因阶梯输入信号导致控制输入饱和的问题,应用采样控制系统直接设计理论,研究了特殊结构下的采样控制系统混合灵敏度设计问题.应用提升技术,给出了提升系统及H∞等效离散控制系统的状态空间模型,并给出了离散控制器的计算方法.实验结果表明,此方法具有实际应用意义.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.
