1、摘要分?jǐn)?shù)階微積分是整數(shù)階微積分的一種推廣,即是將階次推廣到實(shí)數(shù)范圍內(nèi),其誕生于300多年前,發(fā)展到現(xiàn)在,分?jǐn)?shù)階微積分已經(jīng)應(yīng)用于許多的領(lǐng)域,并逐漸發(fā)展成為一個(gè)非常熱門的研究方向。分?jǐn)?shù)階控制系統(tǒng)即用分?jǐn)?shù)階微分方程而非整數(shù)階微分方程來表述的系統(tǒng),與整數(shù)階微分方程表述的系統(tǒng)相比,分?jǐn)?shù)階控制系統(tǒng)可以在本質(zhì)上反映實(shí)際系統(tǒng)的真實(shí)變化過程,所以與利用整數(shù)階控制系統(tǒng)模型相比利用分?jǐn)?shù)階控制系統(tǒng)模型可以比較全面清晰地分析系統(tǒng)。本文給出了分?jǐn)?shù)階微積分的定義及其性質(zhì),分?jǐn)?shù)階控制系統(tǒng)的求解:包括數(shù)值解法和解析解法,并給出了仿真實(shí)例,最后對(duì)分?jǐn)?shù)階控制系統(tǒng)的
