摘要:
脉冲宽度调制 (pulse width modulation，PWM) 驱动是现有伺服控制系统的关键构成，因此在直流电机前端对脉宽信号进行差模滤波与共模滤波尤为重要。以某光电惯性稳定平台WSA38M功放模块为标的搭建滤波电路，分析PWM驱动开关频率导致电机发热和产生电磁耦合干扰的原因，运用公式计算LC滤波电路的电气参数，并进行优化仿真。测试和电磁兼容实验结果表明：优化后的电路性能优良，尤其是在22 kHz~53 kHz频段对系统干扰较小，容易满足整体指标要求，为控制系统设计提供了可靠的依据。
Abstract:The pulse width modulation (PWM) drive plays a pivotal part in the servo driving system. Therefore, the filters become more important in differential mode and common mode for pulse width signal ahead of direct current motors. The filter circuit was built with the WSA38M power amplifier module in a photoelectric inertial stabilized turret. The PWM drive switch frequency was analyzed, which caused motor heating and electromagnetic coupling interference. The electric parameter of LC filter was calculated and the optimization simulation was carried out. The results of test and electromagnetic compatibility experiments show that the optimized electrical performance is excellent, especially the 22 kHz~53 kHz frequency band has less interference to the system, which is easy to meet the overall index requirements, and provides a reliable basis for the control system design.
