商空间理论(粒度计算方法)实现高精度模糊控制

Realizing the High-precision Fuzzy Control Based on the Theory of Quotient Space(Methods of Granular Computing)

该文应用商空间(粒度计算)理论,给出了高精度模糊控制器的实现方法。通过系统控制粒度的不断改变,采用粗粒度粗调、细粒度细调的方法,系统可以兼顾理想的稳态和瞬态性能指标。实践证明以上观点正确。

This paper points out that people can realize t he high-precision fuzzy control by the use of the quotient space theory(a metho d of granular computing).With the changing of control granularity,people can roughly adjust the parameters of control system on the level of coarser granular ity;conversely people adopt the strategy of delicate adjustment to tackle wit h finer granularity,so the system can achieve ideal performance of both stable state and transient state.The above-mentioned turns out to be right in the practices.
