摘要/Abstract

摘要： 针对飞轮速率模式下锁相环控制系统动态响应速度慢和抗干扰能力差的问题,基于建立的磁悬浮飞轮电机锁相环稳速控制系统数学模型,提出了一种锁相环自适应协同控制方法。该方法采用协同控制提高锁相环动态响应速度,并通过自适应律调节环路增益来保证稳速精度,从而提高抗干扰能力。实验结果表明,该方法能够有效提高锁相环稳速控制系统的动态响应速度和抗干扰能力。

Abstract: To increase the dynamic response and interference tolerance of the phase locked loop (PLL) mode control system, a synergetic adaptive PLL control method was presented based on the established mathematical model of PLL motor speed control system. The method utilized synergetic control method to enhance dynamic responses of PLL method and utilized adaptive method to regulate the close loop gain to ensure the precision of rotor speed, increasing interference capability. Experimental results show the effectiveness and feasibility of the presented method in increasing the dynamic response and interference tolerance of PLL method.
