为提高Buck系统的快速跟踪性能，提出了一种改进的离散PID控制策略。在建立Buck电路数学模型的基础上，设计了基于离散PID控制算法的Buck变换器，并对PID控制参数进行了整定，提高了系统效率。仿真结果表明，与常规PID控制相比，利用离散PID控制算法系统在快速性、稳定性、准确性得到显著提高，系统具有较强的鲁棒性。

In order to improve the tracking performance of the Buck system,an improved discrete PID control strategy is proposed. Based on the mathematical model of the Buck circuit,a Buck converter based on discrete PID control algorithm was designed and the PID control parameters are set. The system efficiency was improved. The simulation results show that,com-pared with the conventional PID control algorithm,rapidity,stability and accuracy of the system using discrete PID control algo-rithm is improved more significantly,and the system has stronger robustness.
