一種新的自調(diào)整因子的模糊控制器的仿真研究

在模糊控制規(guī)則的構(gòu)造中，帶有多個(gè)調(diào)整因子的模糊控制規(guī)則雖然比較靈活,方便,但是對(duì)多個(gè)調(diào)整因子的尋優(yōu)要花費(fèi)較大的計(jì)算量,因此難以實(shí)時(shí)實(shí)現(xiàn).尤其是隨著誤差,誤差變化及控制量的論域量化等級(jí)的增加,調(diào)整因子的個(gè)數(shù)也相應(yīng)增加,使得尋優(yōu)過(guò)程變的復(fù)雜.一方面要考慮吸取帶多個(gè)調(diào)整因子的優(yōu)點(diǎn).另一方面又要考慮盡量簡(jiǎn)化尋優(yōu)過(guò)程.更好的滿足實(shí)時(shí)性要求。因此本文設(shè)計(jì)了一種在全論域范圍內(nèi)帶有自動(dòng)調(diào)整因子的控制器.提出了一種新的控制算子,并對(duì)一二階對(duì)象進(jìn)行了仿真試驗(yàn),獲得了良好的控制效果.

The Simulation of Fuzzy Controller With A New adjustable Factor Although Fuzzy Control rules with several factors is flexible and more adjustable,but the optimisation of The factors will take up a lot time , especially with the increasing of the grade in error and error.deritive, the number of factors is increasing ,which lead to the complexion of optimisation, in order to take the merit of factors and simplify the course of optimisation . In this essay the author design a controller, whose factor can be adjusted
in the whole field, By making a simulation on a two-order plant, it takes out a good result
