摘要
针对逆变器在实际应用中难以建立准确的数学模型,传统的PID控制方法在参数整定方面不够灵活,本文提出一种模糊-PID控制方案。该方案将模糊控制和PID控制的优点相结合,对PID参数进行在线调整。仿真结果表明,该控制方案在保证稳态精度的同时改善了动态品质。
In view of the inverter in the practical application is difficult to establish accurate mathematical model, and the traditional PID control method is not flexible, this paper presents a fuzzy-PID control method. This method will blur superiority of fuzzy control and PID control in order to adjust PID parameters online. The simulation result indicated that, this control method caused system to ensure steady state accuracy and improve the dynamic quality.
