模糊自适应整定PID-FS在整流电源中的应用

针对整流电源控制系统被控对象的时变性和多样性,将模糊自适应控制与常规PID控制算法相结合,设计了一种模糊自适应整定PID控制器.在控制算法上,提出了基于模糊自适应整定PID控制器,它很好地解决了传统控制原理中系统控制精度与稳定性之间的矛盾.仿真和实验结果表明,采用模糊自适应整定PID随动系统(Following System,简称FS)的大功率整流电源控制系统能够适应被控对象在较大范围内的变化,具有较强的自适应能力,其控制品质优于常规的PID控制器.

Application of a Following System based on Self-tuning Fuzzy Adaptive PID Control in Rectifier Power Supply

Aiming at diversity and time variation of the controlled object in rectification power supply control system,combining fuzzy adaptive control with common PID control algorithm in this paper,Self-tuning fuzzy adaptive PID con-troller is designed.In the control method,a self-tuning fuzzy adaptive PID controller was used to solve the conflict between stability and control precision.The simulative results show that big-power rectification power supply controller system with self-tuning fuzzy adaptive PID controller is adaptable to the large change of controlled objects and satisfactory adaptive a-bility,whose control quality is superior to common PID controller.
