摘　　要：主要分析了PWM驱动装置的开关频率f对电动加载系统稳定性的影响,给出了整个电动加载系统的数学模型,用朱利稳定判据分析PWM驱动装置的开关频率f对系统稳定性的影响。通过仿真对分析结果进行了验证。The effect of the variation of the chopping frequency of a PWM signal on the stability of a motor load system was mainly investigated. The model of the motor load system was brought forward. The effect of the chopping frequency was analyzed by the method - the Jury test,and the stability limits by the simulation of the system showed that the chopping frequency was one of important parameters for stability of the system.
