分数阶PID控制运用于励磁控制系统

摘要

针对传统的PID(proportion integration differentiation)控制器已难以满足励磁控制系统动态、静态性能以及遏制干扰能力的要求,采用比传统的PID控制器多了两个参数的分数阶PID(FOPID)控制器.该控制器调节的范围更加广泛,能够很好的适应当前励磁控制系统的需要.对其控制器与PID控制器做了对比仿真,结果表明:分数阶PID控制器具有优于传统PID控制器的性能.%In order to improce the dynamic and ststic performamces of the excitation control system and enhamce the ability of restraining disturbance,unadvisablc it is to use still the traditional PID controller for meeting the requirement,so new algorithms should be introdyced.The fractional order PID controller was proposed,in which two parameters more than the traditional PID controller can be regulated.The scope of controlling can be adjusted more widely and the controller can well meet the needs of the current excitation control system.The performance of the controller proposed was compared with that of the PID controller by simulations,The results show that the fractional order PID controller is superior to the traditional one.
