【摘要】 提出一种将传统的滞环比较与定时比较跟踪控制方法相结合的新方法.将两种方法统一起来进行理论分析,得出了跟踪误差带宽、平均开关频率和开关频率的波动范围的解析表达式.传统的滞环比较与定时比较跟踪控制方法都是该方法的一个特例.仿真研究证实了理论分析的正确性.更多还原

【Abstract】 A novel tracing control approach is presented.One kind of apporoach is presented,which combined the hysteresis comparison and timer comparison tracing control,and the analytical expression of track error,everage switching frequency and fluctuate of switchig frequency are obtained.In this analysis,tradtional hysteresis comparison or timer comparison is only particulay case.The simulation is done and demonstrate the validity of the method.更多还原
