摘　　要：针对当前电机控制器使用的控制芯片成本高昂及性能一般的情况,设计使用DSP2808高性能控制芯片研究电压空间矢量控制算法控制交流异步电动机;使用电流传感器和光电编码器采集电机的两相定子电流、转子转速、油门踏板电位器电压为负反馈变量,实现电流环和速度环的带PI调节负反馈的电压空间矢量控制算法产生SVPWM波形,产生的波形驱动光耦控制逆变器;实验测试产生的SVPWM波形符合脉宽不同的7段波要求,能够逆变72V直流电源从而驱动电机,实际测试结果表明此硬件系统的控制电机具有功率大、运行可靠等优点。It is expensive and its performance is low to use the motor controller chip in present. The design uses a DSP2808 to improve the performance, and it is a high--performance control chip to research voltage space vector control algorithm AC induction motor principle. The design uses the current sensor and optical encoder to collect two--phase motor stator current, rotor speed and accelerator pedal potenti- ometer voltage, these can be Negative feedback. Achieve current loop and speed loop with PI regulator feedback voltage space vector control algorithm to generate SVPWM waveform. The Waveform drives opto--coupler to control the inverter. The tests of SVPWM waveforms are different width of 7--segment wave pulse fill the bill, inverter 72V DC power supply to drive the motor, The actual test results show that this hardware system control motor power, reliable operation.
