【摘要】：無(wú)位置傳感器永磁同步機(jī)控制系統(tǒng)已經(jīng)被廣泛地應(yīng)用在各類(lèi)產(chǎn)品中,但是目前的控制系統(tǒng)都存在中低速運(yùn)行不穩(wěn)定的問(wèn)題。影響中低速穩(wěn)定性的因素主要包括啟動(dòng)可靠性,閉環(huán)切換成功率,電流環(huán)以及速度環(huán)穩(wěn)定性。因此,解決中低速穩(wěn)定性問(wèn)題對(duì)于永磁同步電機(jī)的應(yīng)用具有重要意義。基于此,本文設(shè)計(jì)了新型的無(wú)位置傳感器永磁同步電機(jī)中低速控制系統(tǒng)。針對(duì)中低速穩(wěn)定性問(wèn)題,本文將傳統(tǒng)的無(wú)位置傳感器中低速控制算法進(jìn)行了優(yōu)化,實(shí)現(xiàn)了一種基于全維狀態(tài)觀測(cè)器的中低速控制算法,主要做出了三處改進(jìn)：采用預(yù)定位方式啟動(dòng),保障了啟動(dòng)的可靠性：設(shè)計(jì)改進(jìn)型全維狀態(tài)觀測(cè)器算法,提高了電流閉環(huán)和轉(zhuǎn)速閉環(huán)的穩(wěn)定性；優(yōu)化轉(zhuǎn)子位置估算算法,采用鎖相環(huán)方式代替?zhèn)鹘y(tǒng)的反正切方式,提高了閉環(huán)切換成功率。通過(guò)Matlab對(duì)改進(jìn)的算法進(jìn)行建模仿真,驗(yàn)證了算法的可行性。最后,完成了改進(jìn)型中低速控制系統(tǒng)的軟硬件實(shí)現(xiàn),并對(duì)本控制系統(tǒng)進(jìn)行了功能測(cè)試。測(cè)試結(jié)果表明,本文所設(shè)計(jì)的控制系統(tǒng)低速啟動(dòng)無(wú)抖動(dòng),啟動(dòng)可靠；開(kāi)環(huán)可以平滑地切換至閉環(huán)且穩(wěn)定性較高；轉(zhuǎn)速閉環(huán)穩(wěn)定,可以工作在預(yù)定范圍的±5%之內(nèi)；電流閉環(huán)穩(wěn)定,可以工作在預(yù)定范圍的±10%之內(nèi)。本文設(shè)計(jì)的控制系統(tǒng)可直接滿足盤(pán)管風(fēng)機(jī)應(yīng)用,并對(duì)平衡車(chē)、水泵、洗衣機(jī)、空調(diào)等應(yīng)用都有一定的實(shí)用價(jià)值。
[Abstract]:The control system of sensorless permanent magnet synchronous machine (PMSM) has been widely used in all kinds of products, but the current control system has the problem of unstable running at medium and low speed. The main factors affecting the stability of middle and low speed include startup reliability, closed loop switching success rate, current loop and speed loop stability. Therefore, to solve the problem of low-speed stability is of great significance for the application of permanent magnet synchronous motor (PMSM). Based on this, a new low speed control system for sensorless permanent magnet synchronous motor (PMSM) is designed in this paper. In order to solve the problem of low and medium speed stability, this paper optimizes the traditional low speed control algorithm without position sensor, and realizes a low speed control algorithm based on full dimension state observer. Three main improvements are made: starting with predetermined bit mode to ensure the reliability of startup; designing an improved full-dimension state observer algorithm to improve the stability of current closed-loop and rotational speed closed-loop; optimizing rotor position estimation algorithm. The phase-locked loop (PLL) is used to replace the traditional cut-off method, which improves the success rate of closed-loop switching. The improved algorithm is modeled and simulated by Matlab, and the feasibility of the algorithm is verified. Finally, the hardware and software of the improved medium and low speed control system are implemented, and the function of the control system is tested. The test results show that the control system designed in this paper has no jitter at low speed, reliable start, open loop can be smoothly switched to the closed loop and has high stability, the speed closed loop is stable and can work within 鹵5% of the predetermined range, and the current closed loop is stable. It can work within 鹵10% of the predetermined range. The control system designed in this paper can directly meet the application of coil fan, and has certain practical value to the application of balancing car, water pump, washing machine, air conditioning and so on.
