摘　　要：基于BoostDC/DC变换器的双线性大信号模型,直接应用李雅普诺夫稳定性理论,推导出一种新型控制策略,由新型控制律组成的闭环系统具有鲁棒稳定性和良好的输出调节特性。数值仿真和实验结果均验证了该新型控制律的有效性和实用性。A new control law based on the bilinear large signal models is proposed for achieving the output regulation of Boost DC/DC converter. The control law is derived from directly applying the Lyapunov stability theory to the bilinear large signal models, so that the closed loop systems possess excellent output characteristics. Numerical simulations and experiment results have verified the validity and practicability of the new control law.
