【摘要】：在電力電子時(shí)代的今天,大慣性輪伺服系統(tǒng)一直在現(xiàn)代化的生產(chǎn)和生活中起著十分重要的作用。據(jù)資料統(tǒng)計(jì),現(xiàn)在有的90%以上的自動(dòng)控制系統(tǒng)均是來(lái)自于大慣性輪伺服系統(tǒng),并且大慣性輪伺服系統(tǒng)與人們的生活息息相關(guān),密不可分。隨著現(xiàn)代化步伐的邁進(jìn),人們對(duì)自動(dòng)化的需求越來(lái)越高,使得大慣性輪伺服系統(tǒng)向更復(fù)雜的自動(dòng)化控制方向發(fā)展。從系統(tǒng)開發(fā)者的角度,大慣性輪伺服程序通常面臨高并發(fā)和高負(fù)載的壓力。同時(shí),大慣性輪伺服還要面臨來(lái)自越來(lái)越復(fù)雜應(yīng)用領(lǐng)域的挑戰(zhàn)。目前的基于模糊PID控制的大慣性輪伺服系統(tǒng)在電機(jī)運(yùn)轉(zhuǎn)穩(wěn)速、調(diào)速、加速或減速三個(gè)方面仍然不能滿足使用要求。為了克服大慣性輪伺服系統(tǒng)調(diào)速系統(tǒng)的缺點(diǎn),得到高精度的轉(zhuǎn)速,隨著電力電子技術(shù)的發(fā)展,使得比較普遍的用模糊PID調(diào)節(jié)器來(lái)控制電力系統(tǒng)大慣性輪伺服,利用各種新穎的、高性能的控制策略,來(lái)使電力系統(tǒng)大慣性輪伺服平穩(wěn)的運(yùn)轉(zhuǎn),這使大慣性輪伺服系統(tǒng)減少集群中的大慣性輪伺服節(jié)點(diǎn)數(shù),顯著的降低企業(yè)運(yùn)營(yíng)的成本,,從而使得使大慣性輪伺服系統(tǒng)的性能更符合人們的使用要求。在大慣性輪伺服發(fā)現(xiàn)請(qǐng)求提高I/O性能之前,塊層會(huì)對(duì)這些請(qǐng)求排序。如果必要,大慣性輪伺服重新對(duì)這些請(qǐng)求排序。通常這種重新排序通過(guò)傳遞多個(gè)請(qǐng)求到大慣性輪伺服并且使硬件考慮優(yōu)化的順序來(lái)實(shí)現(xiàn)。在調(diào)速系統(tǒng)上位機(jī)的開發(fā)中用到Visual Basic,對(duì)系統(tǒng)功能模塊進(jìn)行實(shí)現(xiàn)。將PID控制和Fuzzy控制二者結(jié)合起來(lái),運(yùn)用模糊數(shù)學(xué)的基本理論方法,把規(guī)則的條件、操作用模糊集表示,并把這些模糊控制規(guī)則以及有關(guān)信息(如評(píng)價(jià)指標(biāo)、初始PID參數(shù)等)作為知識(shí)存入知識(shí)庫(kù)中,以自動(dòng)實(shí)現(xiàn)對(duì)PID參數(shù)的最佳調(diào)整。對(duì)系統(tǒng)功能進(jìn)行測(cè)試,從性能角度分析了服務(wù)模型的狀況。本文將介紹一種基于模糊PID控制的大慣性輪伺服系統(tǒng)�；诎胪桨氘惒降木�程池方式進(jìn)行設(shè)計(jì),避免了系統(tǒng)阻塞或大量線程帶來(lái)的開銷,是系統(tǒng)高效運(yùn)行的基礎(chǔ),本設(shè)計(jì)選用AT89S52單片機(jī)作為信號(hào)產(chǎn)生器,應(yīng)用模糊PID算法,對(duì)整個(gè)過(guò)程進(jìn)行位置跟蹤,模糊PID控制,在設(shè)計(jì)制作的過(guò)程中,考慮到實(shí)際需求鍵盤輸入模塊和LED顯示部分,使本設(shè)計(jì)的實(shí)用性得到了增強(qiáng)。
[Abstract]:In the era of power electronics, the large inertial wheel servo system has been playing a very important role in modern production and daily life. According to the statistics, some 90% of the automatic control systems come from the large inertia wheel servo system. And the large inertia wheel servo system is closely related to people's life. With the step of modernization, the demand for automation becomes higher and higher. The development of large inertial wheel servo system towards more complex automatic control. From the point of view of system developer, large inertia wheel servo program usually faces high concurrency and high load pressure. At the same time, Large inertial wheel servo has to face challenges from more and more complex application fields. The current large inertial wheel servo system based on fuzzy PID control is running at steady speed and adjusting speed. In order to overcome the shortcomings of large inertia wheel servo system and get high precision speed, with the development of power electronics technology, The fuzzy PID regulator is widely used to control the large inertia wheel servo in power system, and various novel and high performance control strategies are used to make the large inertia wheel servo run smoothly in the power system. This makes the large inertia wheel servo system reduce the number of large inertia wheel servo nodes in the cluster. Significantly reduce the operating cost of the enterprise, thus making the performance of the large inertia wheel servo system more responsive to people's requirements. Before the large inertia wheel servo discovery request improves the I / O performance, the block layer sorts these requests, if necessary. The large inertial wheel servo reorders these requests. This reordering is usually achieved by passing multiple requests to the large inertia wheel servo and allowing the hardware to consider the order of optimization. Visual is used in the development of the upper computer of the speed control system. Basic, the system function module is implemented. The PID control and Fuzzy control are combined. By using the basic theory and method of fuzzy mathematics, the condition and operation of rules are represented by fuzzy sets, and these fuzzy control rules and relevant information (such as evaluation index, initial PID parameters, etc.) are stored in the knowledge base as knowledge base. In order to automatically realize the best adjustment of PID parameters, the function of the system is tested, In this paper, a large inertia wheel servo system based on fuzzy PID control is introduced. The design is based on a semi-synchronous and semi-asynchronous thread pool, which avoids the overhead caused by system blockage or a large number of threads. This design chooses AT89S52 single chip computer as signal generator, uses fuzzy PID algorithm, carries on the position tracking to the entire process, the fuzzy PID control, in the process of design and manufacture, Considering the actual requirement of keyboard input module and LED display, the practicability of this design is enhanced.
