摘　　要：首先给出了自稳定控制的物理概念及其基于滤波器的实现思路,同时依据PWM控制DC/DC变换器系统的分段线性特点,提出了一种新的Jacobian矩阵求解方法,将其应用于自稳定控制峰值电流模式Boost变换器系统,实现了反馈控制参数优化分析,最后给出了有关的仿真和实验结果,验证了文中所提控制方法的有效性和理论分析的正确性。A physical concept of self-stable control is presented in this paper and its filter based realization is derived as well.In addition,according to the piecewise-linear characteristic of PWM controlled DC/DC converter,a new Jacobian-matrix solution method is proposed and with its application to the peak-current mode Boost converter with self-stable control.The optimization of control parameters of the self-stable controller is achieved.The feasibility of the proposed control method and the correctness of the theoretical analysis are confirmed by the simulation and experimental results which given in the last part.
