摘要
针对传统的交-交变频器调速系统存在的不足,文章将自适应控制的概念引入到交-交变频器理论中,引入了专家PID控制算法,建立了专家知识库,利用专家控制策略,实行在线自动修正PID参数以及改变控制策略,使系统适应在不同工作状态下的特性。基于Matlab建立交-交变频器的仿真模型,该设计运用专家PID控制算法编写仿真程序进行了仿真研究,对仿真结果进行了分析研究,最终验证了自适应调速策略能够提高交-交变频器的调速精度的结论。
Aimed at the shortcomings of the traditional cycloconverter speed regulation system,this paper introduces the concept of adaptive control into the cycloconverter theory,introduces the expert PID control algorithm,establishes the expert knowledge base,uses the expert control strategy,implements the online automatic correction PID parameters as well as changing control strategies to adapt the system to different operating conditions.The simulation model of cycloconverter was established based on Matlab,the simulation program was programmed by expert PID control algorithm,and the simulation results were analyzed.Finally,the conclusion was reached that the adaptive speed regulation strategy can improve the speed regulation accuracy of cycloconverter.
