摘要
预测控制是一种基于模型的先进控制技术,所采用的预测控制算法对模型的精度要求不高,比传统的最优控制和自适应控制更适应复杂的工业工程过程中不确定环境的需要。提出了一种基于预测模型预测系统未来输出、滚动实施优化并结合了闭环反馈校正的计算机优化控制算法,采用滚动的有限时段优化取代了一次性的全局优化实现滚动优化控制,更符合实际工业过程控制的特点,对克服系统的不确定性影响具有更强的鲁棒性。利用提供的优化控制算法,在实际应用中取得了较好的效果。
The forecast control is one kind advanced model - based control technology. The forecast control algorithm is more adapted in the complex industrial engineering process than the traditional optimum control or the adaptive control. It proposes one kind control algorithm based on the forecast model that can predicate the output of system and optimize the process combined with the closed loop feedback. In the limited time it can realize the optimization to instead of the one-off global optimization. This algorithm is more suitable for the actual industry process control characteristic, and more stronger robustness to overcame the system of the uncertainty influence. The application shows that the control algorithm can obtain the good effect.
