| 摘 要： | 将电力电子系统的最优控制问题变换为参数最优化问题。以正激开关稳压电源为例，建立其控制器小信号离散参数最优化模型，应用一种离散非线性规划算法求解。得到在加权ＩＳＥ最小意义下并在工程上可实现的控制器最优参数。用ＳＰＩＣＥ－２仿真，比较了用连续与离散两种非线性优化算法设计的正激开关电源瞬态响应及频率特性．

| Abstract: | The optimal control problem of a power electronic system is transformed into a parameter optimization problem. A small signal discrete optimization model for the controller design of a forward swit. ching regulator is built. A discrete nonlinear programming technique is introduced. A set of realistic optimal parameters of the controller, in the sense of minimizing an augmented ISE index, is generated automatically. The transient responses of two forward switching regulators whose controllers are designed separately by continuous and discrete optimization methods are verified and compared by SPICE-2 simulations. |
