【摘要】：內(nèi)置式永磁同步電機(IPMSM)以其體積小、結(jié)構(gòu)簡單、功率密度高、可靠性好等優(yōu)點,廣泛應(yīng)用于各種高性能調(diào)速場合。在化工制造方面也有廣泛的應(yīng)用,如石油精煉,金屬材料,塑料合成,食品加工和催化制造等。永磁同步電機無傳感器控制技術(shù)是當前交流調(diào)速領(lǐng)域的一個研究熱點,它不僅可以節(jié)省成本,而且可以增加整個系統(tǒng)的魯棒性。與其它轉(zhuǎn)子位置估算方法相比較,高頻信號注入法更適合于零速和低速場合。因此,本文提出了模糊控制結(jié)合高頻信號的注入來研究對電機的控制。本文重點解決智能方法控制高頻信號注入法在內(nèi)置式永磁同步電機中轉(zhuǎn)子位置估算的問題。本文首先介紹了內(nèi)置式永磁同步電機的數(shù)學(xué)模型和矢量技術(shù)原理;分析了模型參考自適應(yīng)(MRAS)應(yīng)用于電機低速時的控制。并進一步分析旋轉(zhuǎn)高頻信號注入法對低速時電機控制的優(yōu)勢,在此優(yōu)勢上分別分析了 id=0、最大轉(zhuǎn)矩/電流比(MTPA),和旋轉(zhuǎn)高頻信號注入法對永磁同步電機矢量控制的影響;模糊PI控制器較傳統(tǒng)PI速度調(diào)節(jié)器的優(yōu)點。其次,為得到轉(zhuǎn)子精確的參數(shù)值,構(gòu)建了模糊PI、同步軸系高通濾波器(SFF)、全維觀測器及外差法的仿真結(jié)構(gòu)圖,并在MTALB/Simulink中搭建了四種無傳感器矢量控制系統(tǒng):模型參考自適應(yīng)法(MRAS)、id=0高頻信號注入、MTPA高頻注入和模糊控制高頻注入法;就此幾種無傳感器算法在永磁同步電機控制中進行仿真分析,結(jié)果表明高頻信號注入法更適用于低速永磁電機矢量控制。針對電機控制系統(tǒng)的速度環(huán),因負載直接作用在電機而產(chǎn)生的擾動,如果僅采用PI控制,很難滿足系統(tǒng)的快速響應(yīng)需求。本文采用模糊PI高頻信號注入法,并在永磁同步電機中進行了仿真驗證。仿真結(jié)果表明了模糊控制的高頻載波注入法估算轉(zhuǎn)子位置的誤差有所減小并且提高系統(tǒng)的快速性。
[Abstract]:Built-in permanent magnet synchronous motor (IPMSM) is widely used in various high performance speed regulation occasions because of its small size, simple structure, high power density, good reliability and so on. It also has a wide range of applications in chemical manufacturing, such as petroleum refining, metal materials, plastic synthesis, food processing and catalytic manufacturing. Sensorless control technology of permanent magnet synchronous motor (PMSM) is a hot research topic in the field of AC speed regulation at present. It can not only save cost, but also increase the robustness of the whole system. Compared with other rotor position estimation methods, the high frequency signal injection method is more suitable for zero speed and low speed situations. Therefore, fuzzy control combined with high frequency signal injection is proposed to study the control of motor. In this paper, the problem of rotor position estimation in built-in permanent magnet synchronous motor (PMSM) controlled by intelligent method of high frequency signal injection is solved. In this paper, the mathematical model and vector technology principle of built-in permanent magnet synchronous motor (PMSM) are introduced, and the application of model reference adaptive (MRAS) to motor control at low speed is analyzed. The advantages of rotating high frequency signal injection method on motor control at low speed are further analyzed, and the effects of id=0, maximum torque / current ratio (MTPA), and rotating high frequency signal injection method on vector control of permanent magnet synchronous motor (PMSM) are analyzed, and the advantages of fuzzy PI controller over traditional PI speed regulator are analyzed respectively. Secondly, in order to obtain the accurate parameters of rotor, the simulation structure diagram of (SFF), full-order observer and heterodyne method for fuzzy PI, synchronous shafting high-pass filter is constructed, and four sensorless vector control systems are built in MTALB/Simulink: model reference adaptive (MRAS), id=0 high frequency signal injection, MTPA high frequency injection and fuzzy control high frequency injection; Several sensorless algorithms are simulated and analyzed in permanent magnet synchronous motor (PMSM) control. The results show that the high frequency signal injection method is more suitable for vector control of low speed permanent magnet motor (PMSM). For the speed loop of the motor control system, the disturbance caused by the direct action of the load on the motor, if only PI control is used, it is difficult to meet the fast response requirements of the system. In this paper, the fuzzy PI high frequency signal injection method is used and verified by simulation in permanent magnet synchronous motor (PMSM). The simulation results show that the error of estimation of rotor position by high frequency carrier injection method based on fuzzy control is reduced and the rapidity of the system is improved.
