| 摘 要： | 在ＰＷＭ开关稳压电源的双线性模型及Ｌｉａｐｕｎｏｖ渐近稳定性理论的基础上．给出了这类系统的线性反馈控制律设计的新方法。这一大信号设计方法可使开关稳压电源有较满意的局部稳定域和瞬态响应，而所需控制能量较小。文中以双环ｂｏｏｓｔ开关稳压电源为例进行设计，并用离散时域数字仿真法对大信号扰动下的瞬态响应进行仿真。

| Abstract: | : A new method is presented for the design of linear feedback control laws for PWM switching regulators based on the bilinear model and Liapunov asymptotical stability theorem. The resulting feedback amplification matrix for the switching regulators designed by the large signal method guarantees a satisfactory stability region in the state space, and meets the requirements of large damping on transient responses with smaller feedback control energy. A two-loop boost switching regulator is taken as a design example. Large signal transient responses are simulated by the discrete time domain simulation technique. |
