摘要:
针对开关电源的复杂性和时变性,传统PID控制器整定方法无法很好满足其控制性能要求的问题,提出一种面向性能指标的最优PID控制器参数整定方法。基于DP算法,计算保证闭环系统稳定的PID控制器参数范围;利用具有全局寻优能力的遗传算法,按照ITAE性能指标在该范围内进行参数寻优。以BUCK变换器为利的仿真研究表明,该方法在指定的性能指标上取得了满意的控制效果,在负载发生摄动时,较传统PID控制器,具有较好的鲁棒性,且计算相对简单、实用性强,可推广到非线性PID控制器的参数整定和相关工程实践中。
Abstract:
Due to the time-variable and complexity of the switching mode power converters,the conventional parameter tuning method for PID controller cannot satisfy the control performance demand.In this paper,a new parameter tuning method for performance-oriented optimal PID controllers is proposed.The DP algorithm was used to calculate the PID controller parameter region which stabilizes the closed-loop system including buck converters.Then the genetic algorithm with global searching was used to select optimum parameters from the region based on ITAE performance criteria with overshoot penalty.The simulation results for the BUCK switching converter show that the proposed method demonstrates good stability for the specified indices and more robust performance than the traditional methods under perturbations of the load parameters;furthermore it needs less relatively calculation and are more practical.Meanwhile it can also be applied in parameter tuning for nonlinear PID controllers and corresponding projects.
