摘要
交流电机变频调速方式在频率范围、输出性能、功率因数、工作效率、动态响应、调速精度、低频转矩、使用方便等方面是以往的交流调速方式无法比拟的,其优越性体现在两个方面:一是节电显著;二是卓越的调速性能。
电压空间矢量是在电机统一理论、机电能量转换和坐标理论的基础上发展起来的,具有先进性、新颖性和实用性的特点。首先本文通过坐标变换,将定子电流矢量分解为按转子磁场定向的两个直流分量,从而实现磁通和转矩的解耦控制,达到直流电机的控制效果。其次,文中设计了转速和电流调节器,采用基于单神经元的PI控制的方法,并且对系统进行了MATLAB仿真,仿真结果表明控制系统具有更好的稳定性和鲁棒性。然后,根据电机参数要求,设计了变频系统的主电路、电流采样电路、转速检测电路、过流过压等保护电路和键盘显示电路,并搭建了基于数字信号处理器TMS320F2812的实验平台。最后利用CCS操作平台编写了整个系统的主程序和中断模块的程序,重点介绍了SVPWM中断程序中的电流采样程序和转速检测程序。并在实验平台上运行系统程序,利用数字示波器测得在50Hz时期的SVPWM波形。
AC motor frequency control methods in the aspect of frequency range,output performance,power factor,efficiency,dynamic response, speed precision, low-frequency torque, ease of use and ect. is better than that of the past.And its superiority is reflected in two aspects: one is the prominence of saving power;the other is the preeminent governing performance.
Voltage space vector is based on motor unification principle,energy conversion and vector coordinate transformation theory. It has many advantages such as advanced, novelty and practicality. Firstly, by transforming coordinate,the stator current is decomposed into two DC parts which orientated as the rotator magnetic field and controlled respectively in this paper. So magnetic flux and torque are decoupled.It controls the asynchronous motor as a synchronous way. Secondly, the thesis designs the speed and current regulator which based on single neuron PI control method. And the thesis uses MATLAB simulation for the entire system, the simulation results shows that the control system has better stability and robustness. Thirdly, according to motor parameters required the thesis designs the main circuit of the inverter system, the current sampling circuit, speed detection circuit,overcurrent-overvoltage protection circuits,keyboard display circuit and built a digital processor TMS320F2812-based experimental platform.Finally,by using code composer studio(ccs)experimental platform,the thesis compiles the main program of the whole system and the program of the interrupt module. The thesis discusses the current sampling procedures and speed of testing procedures in details,which belongs to the interruption of programs SVPWM.The program of the whole system is run in the experimental platform. The digital oscilloscope measures SVPWM waveform at 50Hz.
