【摘要】：隨著工業(yè)自動化水平的不斷發(fā)展，在許多工業(yè)過程中，一臺電機已經(jīng)難以滿足其要求，而需要對兩臺電機進行同步的控制，因此在很多對轉(zhuǎn)速和精確度都有很高要求的系統(tǒng)中雙電機同步控制都是亟待解決的問題。為了提高雙伺服電機控制系統(tǒng)的同步性能，在結(jié)合國內(nèi)外相關(guān)文獻及自動控制理論的基礎上，對雙電機同步控制系統(tǒng)進行了控制結(jié)構(gòu)的設計以及控制算法的研究。 本文對雙軸伺服電機在工業(yè)領域中應用最為廣泛的制袋機生產(chǎn)線研究的基礎上，根據(jù)其功能要求對雙軸伺服電機控制系統(tǒng)進行了詳細分析研究。 為了實現(xiàn)對雙軸伺服電機進行同步控制，并驗證和設計高效的控制系統(tǒng)，首先對雙軸伺服電機控制系統(tǒng)建立動態(tài)的數(shù)學模型，建立永磁同步電機的三相靜止、兩相靜止、兩相旋轉(zhuǎn)坐標系，在坐標變換的過程中給出了電壓方程、轉(zhuǎn)矩方程和磁鏈方程。本伺服系統(tǒng)中的永磁同步電機采用i d=0的矢量控制方式，，引入主從控制思想和SVPWM算法，通過對主電機和從動電機進行給定和偏差反饋，利用PI調(diào)節(jié)完成對調(diào)節(jié)器的設計，以MATLAB/Simulink軟件為平臺對建立模型中的電壓、轉(zhuǎn)矩、PWM輸出脈寬進行仿真分析。然后在數(shù)學模型和DSP控制技術(shù)的基礎之上，建立控制模塊，如SPEED模塊和SVPWM模塊等，并用TMS320F2812搭建硬件平臺，完成對事件管理器的配置和相關(guān)檢測模塊的設計。軟件編寫完成后，在CCS軟件平臺下對電機的轉(zhuǎn)速控制、脈寬調(diào)制等進行仿真分析。 本文研究的雙軸伺服電機同步控制的方法，可以在準確對兩臺電機進行控制的同時保證電機的同步性。
[Abstract]:With the continuous development of industrial automation level, in many industrial processes, one motor has been difficult to meet its requirements, and it is necessary to control the two motors synchronously. Therefore, in many systems with high speed and precision, the synchronous control of dual motors is an urgent problem to be solved. In order to improve the synchronization performance of the dual servo motor control system, the design of the control structure and the control algorithm of the dual motor synchronous control system are studied on the basis of domestic and foreign literature and automatic control theory. Based on the research on the production line of double axis servo motor, which is widely used in industry, the control system of double axis servo motor is analyzed and studied in detail according to its function requirement. In order to realize synchronous control of two-axis servo motor and to verify and design an efficient control system, a dynamic mathematical model is established for the two-axis servo motor control system, and the three-phase static and two-phase static of the permanent magnet synchronous motor are established. In the two-phase rotating coordinate system, the voltage equation, torque equation and flux chain equation are given in the process of coordinate transformation. The permanent magnet synchronous motor in this servo system adopts the vector control mode of I DX 0, introduces the master-slave control idea and SVPWM algorithm, through the given and deviation feedback to the main motor and the slave motor, completes the design of the regulator by using Pi regulation. Based on MATLAB / Simulink software, the voltage, torque and PWM output pulse width of the model are simulated and analyzed. Then, on the basis of mathematical model and DSP control technology, the control module, such as Speed module and SVPWM module, is established, and the hardware platform is built with TMS320F2812 to complete the configuration of event manager and the design of related detection module. After the completion of the software, the speed control and pulse width modulation of the motor are simulated and analyzed under the CCS software platform. The method of synchronous control for two axis servo motors studied in this paper can guarantee the synchronism of the two motors while accurately controlling the two motors.
