大惯性系统的自适应起动控制

针对过程的起动段给出了一种预报控制策略。算法在起动段可以不依靠任何预辨识即可对过程的未知参数进行在线估计,在避免了超调和过渡过程时间过长的同时,过程可以很快地达到稳态,而且通过起动段积累起来的过程信息仍可用于稳态工作时的控制器调节,为了验证算法的性能,将其与常规的开关控制器在起动段的性能进行了比较。

Adaptive Start-up Control for Sluggish Processes

This paper presents a predictive control strategy for the start-up phase of pro-cesses. The algorithm concerned estimates the parameters of the unknown process on--lineduring start-up without any pre-identification. The process reaches the stationary phasequickly while avoiding as the algorithm does undesired states of the process such asovershooting and/ or long settling-time. The process information gathered during thestart-up phase can also be of use for adjusting a controller for the stationary operation.The results of this algorithm are compared in start-up procedures with that ofconventional on-off controllers in order to verify the performance of the algorithm.
