摘要: 该文提出了一种新的并行处理自适应控制算法.该算法将自适应控制中辨识和控制算法 分为运行时间相当的两大部分,在每个控制间隔内,两部分交换信息后分别同时计算,从而在 任务级上实现了并行处理.文中讨论了并行算法流程及性能评价指标,并给出了在制导系统 中的应用实例.试验表明,通过双机并行处理,自适应控制的处理速度有显著提高.Abstract: In this paper, a new parallel adaptive control algorithm is presented. In this algorithm, the identification and control algorithms are separated in two parts with almost equal length for execution. In each control period, the two parts separately and concurrently compute after exchanging related information, so that the parallel processing is realized at task level. The flow process of algorithm and index of performance evaluating are also discussed. An example in guidance systems is given. It is shown that the processing speed of adaptive control have been enhanced through parallel processing in double processors.
