The embeded system energy consumption scheduling process control, by the interference of the external environ-ment of the thermal noise is large, the control performance is not good, the traditional methods of anti-interference design of self correlation matched filtering method, the filtering effect of the thermal noise of the broadband interference with the poor. Put forward a kind of based on particle filtering cross-correlation interference filtering system model of the energy consumption of embedded system, the energy consumption of the process control, process control hardware system design of the embedded system, the signal model of interference noise control precision of extracting effect, improved design of matching filter based on particle filter, to improve the control precision, the simulation results show that, using the model can effectively achieve the wideband thermal noise with interference filter, to improve the energy consumption of embedded system process control accuracy, reduce the energy consumption of the control error, in the design and applications of em-bedded system, it has good practical value.
