| 摘 要： | 建立带恒功率负载的buck变换器模型,针对该模型采用DP算法分析变换器的PID控制器的稳定性空间,得出PID控制稳定域。采用ITAE性能指标为目标函数,在PID稳定域内寻找最优控制参数,得出PID控制器。并通过仿真对其控制效果进行验证。结果表明：该PID控制器和传统方法整定的PID控制比较,有良好的动态和稳定性能,有一定的应用价值。

| Abstract: | The buck converter model with constant power load is built.For the model,use the stability space of PID controller of DP algorithmic analysis converter to get PID control stable region.Use ITAE Performance index to be objective functions,which searches for optimal control parameters in PID stable region to get PID controller.The control result has been verified by simulation.The result shows the PID controller,compared with PID control of the traditional method,has fine dynamic and stable performance and so... |
