项目摘要

As to the application of adaptive control theory to real systems, head investigator and his colleagues recently proposed very effective and practically realizable adaptive control method, which is called as Simple Adaptive Control(SAC) method. The main aim of the research was to establish the decentralized SAC scheme for large-scale systems from both theoretical and experimental point of view. The research results are summarized as follows.1.Establishment of the decentralized simple adaptive control method.We developed a concrete design method of decentralized simple adaptive control which guarantees the stability of closed-loop system. Further a robust decentralized simple adaptive control system was also considered which reduces the interaction of subsystems adaptively. The latter means the success of the realization of the autonomy of the decentralized control system. These results are published on the Transactions. of SICE and presented at the 12th IFAC world Congress and so on as listed in the term 11.2.Confirmation of effectiveness of the proposed methods by experimentsThe obtained theoretical results were applied to the vibration control of 5th-degree-of-freedom structure and examined the effectiveness of the proposed methods. In this case, the decentralized SAC algorithm can be simplified by using the physical constraints of the structures. Experimental results were very well and high performance vibration suppression for earthquake-like disturbance was attained. These results were presented at 1994 JSME Design and Dynamics Conference and 5th Asia-Pacific Vibration Conference and so on as listed in the term 11.As stated above, the expected purpose of the research was attained almost completely.

关于自适应控制理论在真实的系统中的应用，最近，研究者和他的同事们提出了一种非常有效的、实际上可实现的自适应控制方法，称为简单自适应控制（SAC）方法。本研究的主要目的是从理论和实验两个角度建立大系统的分散SAC方案。主要研究成果如下：1.分散简单自适应控制方法的建立提出了一种保证闭环系统稳定性的分散简单自适应控制的具体设计方法。此外，还考虑了鲁棒分散简单自适应控制系统，自适应地减少子系统之间的相互作用。后者意味着分散控制系统自治性的成功实现。这些结果在交易中公布。第11.2项中所列的SICE和第12届IFAC世界大会上提出的方法等。通过实验验证所提方法的有效性将所得理论结果应用于五自由度结构的振动控制，验证了所提方法的有效性。在这种情况下，分散SAC算法可以通过使用结构的物理约束来简化。实验结果表明，该方法具有良好的抗地震干扰性能。这些结果已在1994年JSME设计与动力学会议和第五届亚太振动会议等会议上发表。
