Fuzzy rule base, time delay systems.
In time delay control systems, the observed information is related to a past instant and using this delayed signal may cause unsatisfactory results in control system applications. This paper deals with how time delay information can be used in reorganizing the rule base so as to improve system performance. Basically, it proposes a new scheme of appropriate shifting of the rule base to compensate the information lag caused by time delay in the system. The parameters affecting the shifting scheme are discussed in detail and the shifting scheme is tabulated with respect to system model parameters. Applications of the new methodology in different systems are simulated and the effectiveness of the scheme is fully illustrated.
