Abstract


This article Boost converter for the object , and focus on the topology of new nonlinear control and intelligent control algorithm APFC system . The conventional average current method is necessary to detect a Boost converter input voltage, input current and the output voltage , the control circuit becomes complicated , the nonlinear distortion of the multiplier also increases the ripple content of the system , we studied a novel input current shaping technology ( ICST ) . As the inverse process of the the traditional average current law , ICST technology topology is simple, without the multiplier , the input current to track the input voltage in a switching cycle , the theoretical analysis and simulation results show that dynamic better , APFC system resistance simulation \APFC system control object nonlinear and time-varying characteristics of the traditional PID control is difficult to achieve satisfactory results , this paper, intelligent control method to improve the capacity of the system 's anti- load disturbance . Fuzzy control and single neuron control can take advantage of its nonlinear variable structure , look for classy advantages to overcome the shortcomings of the traditional PID control , and thus the ability to improve the system of anti - load disturbance . Simulation studies have shown that the two advanced PID controller is better than the traditional PID controller . Finally the control core TMS320F2812DSP chip based on single neuron control algorithm APFC system 's hardware and software design .
