| 摘 要： | 针对参数不确定交流位置伺服系统,传统控制方式虽然设计简单,并保证系统具有较好的稳态性能,但无法确保系统的鲁棒性.本文针对这一情况,提出了一种基于状态变换的鲁棒二次最优控制策略,该方法在保持传统控制结构不变、系统具有较好稳态性能同时,又大大增强了系统对参数摄动的鲁棒性.实验证明,该方法实现简单、控制效果良好.

| Abstract: | For solving the problems in traditional control means for AC servo system with parameter uncertainty, a robust quadric optimal control method has been put forward, which is based on state transformation. This control method not only remains conventional control structure and its advantage on static performance, but also greatly increases robustness to changes in system parameters as dynamic performance by treating the whole system with PI Controller and state feedback as a higher-ranked plant. Experiment has demonstrated the implementation simplicity and effectiveness of this control method. |
