摘要
提出一种基于自适应PID的高频手术器控制系统。在高频手术器系统切割和凝血过程中,须及时根据情况改变相应的功率输出给定值,传统的PID控制方法的动态响应速度和超调不能够满足高频手术器系统的需要。因此文章提出了自适应改变系统PID偏差大小的控制算法,实验结果表明该控制算法动态响应速度快,控制效果较好。
A kind of Electrosurgical-generator system that based on self-adaptive PID controller is introduced.During the cutting and blood-coagulation in the Electrosurgical-generator system,power output must be changed according to the corresponding given value.And the dynamic response and overshoot of the traditional PID control methods can not meet the need of Electrosurgical-generator system.Therefore,this paper proposes a algorithm which adaptively changes the deviation of the PID controller.The experimental results show that the control algorithm improves dynamic response speed and has preferable effects.
