| 摘 要： | 根据V^2控制原理，用状态空间平均和线性化方法分别建立BUCK变换器和其控制环的数学模型，求出整个系统的传递函数，并根据优化控制理论对控制环补偿电路的参数进行优化．仿真结果表明，经优化设计的BUCK变换器比根据经验值设计的变换器的响应速度提高约50％，带宽增加约4倍．

| Abstract: | The models for BUCK converter and controlling loop were built using state-space average and linear methods and V~2 control technique, and the parameters for the compensative circuit in the controlling loop were optimized based on optimal control theory. The simulation results show that the transient speed of the optimized Buck converter is 50% faster and the bandwidth is about 4 times wider than that designed according to common practices. |
