【正文】 現(xiàn)使得磁性能有了較大程度的提升。十九世紀二十年代世界上誕生了首個永磁體電機,當時天然的鐵礦石被充作永磁體電機的永磁體,由于這個原因使得永磁體電機體積異常的大,為應用所轉(zhuǎn)運帶來不便。模擬仿真可以在實驗環(huán)境下,在可操控條件下,將傳統(tǒng)的具有一定危險性的實物試飛用可多次反復的模擬仿真來替代,對飛行器的相關(guān)技術(shù)參數(shù)多次實驗,以改善其性能指標,最終使得所設計的飛行器有更合理的技術(shù)參數(shù)。利用計算機仿真,在給出特定技術(shù)參數(shù)的基礎(chǔ)上,通過計算機技術(shù)模仿實物的實驗,避免了實驗所帶來 的危險性,而更為重要的是仿真在保證實驗數(shù)據(jù)真實性的基礎(chǔ)上,與實物試飛相比具有極大的經(jīng)濟優(yōu)勢。多種航天器在試飛的過程中若采用實物進行試驗,需要大量的人力及財力的支持,且試驗時具有一定的安全隱患。在人類的發(fā)展歷程上,人們不斷研制出各種航天器進行太空探索活動。 low speed control system。 關(guān)鍵詞 :重復控制;永磁電機;低速控制系統(tǒng);設計原理 Abstract:with the rapid development of power electronic technology, microelectronics technology, motor control theory and rare earth permanent mag materials, the permanent mag synchronous motor (P M S M) can be used quickly. In addition to the general characteristics of synchronous motor, permanent mag synchronous motor has the advantages of high efficiency, simple structure, small inertia, good maintainability and so on. Therefore, it is widely used in flexible manufacturing systems, industrial robots, office automation, CNC machine tools and aerospace, etc.. Because of the permanent mag synchronous motor is a nonlinear system, multivariable, strong coupling, using the traditional P I D control method is easily affected by motor parameter variations and load disturbances and other uncertain factors. In order to improve the dynamic and static characteristics of the control system, the new control theory and intelligent control theory can be used instead of PID control, such as sliding mode control, neural work control, fuzzy control and so on. In this paper, the repetitive control is used to design the low speed control system of permanent mag motor. Key words: repetitive control。為了提高控制系統(tǒng)的動態(tài)和靜態(tài)特性,可以采用新型控制理論和智能控制理論代替 PID 控制,比如滑??刂啤⑸窠?jīng)網(wǎng)絡控制、模糊控制等。因此,廣泛應用于柔韌性制造系統(tǒng)、工業(yè)機器人、辦公自動化、數(shù)控機床以及航空航天等領(lǐng)域。I 重復控制
