两种常用的方法来减轻噪声对过程输出的影响是鲁棒参数设计和在线控制。在许多过程中,最优控制律依赖于参数设计解,反之亦然。因此,显然需要采取一种将这两种方法结合起来的综合办法。本文提出了一种参数设计方法,在反馈控制的存在下,长时间的过程。系统遵循纯增益动态模型被认为是最佳比例积分和最小均方误差控制策略的鲁棒参数设计。最后,以某尿素包装厂为例进行了仿真分析。
Two commonly used methodologies for mitigating the effect of noise on process output are robust parameter design and on-line control. In many processes, the optimal control law depends on the parameter design solution and vice versa. The need for an integrated approach that combines the two methods is therefore evident. This article develops a parameter design methodology in the presence of feedback control for processes of long duration. Systems that follow a pure-gain dynamic model are considered and the best proportional-integral and minimum mean squared error control strategies are developed using robust parameter design. The proposed method is illustrated using a simulated example and a case study in a urea packing plant.
