Servo System Based on Voltage Space Vector Algorithm

通过导弹舵机交流化提高舵机的工作效率、控制可靠性及功率密度,达到弹体轻型化、小型化的目的。为使导弹舵机交流伺服控制器具有谐波含量少、高频噪声小的正弦电流波形输出,引入了电压空间矢量(SVPWM)算法,并建立了基于SVPWM算法的扇形区判断算法及PWM波生成函数。提高了导弹舵机交流伺服系统的控制性能。通过实验验证了方案的可行性,最终通过参数对比得到了满足导弹舵机工作要求的交流伺服系统。

Through the exchange of missile steering servo to improve work efficiency,reliability and power density control to achieve lightweight airframe,miniaturization purposes. For the output of the sinusoidal current waveform,which has less harmonic content,high-frequency noise in the AC servo controller,a voltage space vector algorithm was performed in this paper. And due to the SVPWM algorithm,a fan-shaped area decision algorithm and PWM wave generating function were brought in.Thus,it improves the performance of control further. Experiments showed the feasibility and met the work requirements of missile servo AC servo system by parameter comparison.
