摘　　要：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。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 controller 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 ability,whose control quality is superior to common PID controller.
