【摘要】：大功率射频激光器的输出功率存在较高的动态性和滞后性,无法采用有效的数学模型描述输出功率的控制过程。传统PID射频激光电源功率控制器,存在响应效率低以及抗干扰性差的问题。因此,设计一种基于Fuzzy-PID控制技术的大功率射频激光电源功率控制器,其基于输入控制指令形成不同占空比的PWM波,控制射频激光电源的功率,确保激光器程序连续/脉冲可调状态。设计了大功率射频激光电源功率控制器结构,对其硬件的各组成部分进行设计,软件部分分析Fuzzy-PID控制器基本原理,采用Fuzzy-PID控制技术完成激光输出功率的反馈控制,稳定激光输出功率,同时设计射频电源调制器的串口通讯界面以及Fuzzy-PID子程序的设计。实验结果说明,所设计控制器具有较高的响应效率和抗干扰性。
[Abstract]:The output power of high power RF laser is highly dynamic and lag, so it is impossible to use an effective mathematical model to describe the control process of output power. The traditional PID RF laser power controller has the problems of low response efficiency and poor anti-interference. Therefore, a power controller for high power RF laser power supply based on Fuzzy-PID control technology is designed, which forms different duty cycle PWM waves based on input control instruction to control the power of RF laser power supply. Ensure continuous / pulse tunable state of laser program. The structure of high power RF laser power supply power controller is designed. The hardware components of the controller are designed. The basic principle of Fuzzy-PID controller is analyzed in the software part, and the feedback control of laser output power is accomplished by using Fuzzy-PID control technology. At the same time, the serial communication interface of RF power modulator and the design of Fuzzy-PID subprogram are designed. The experimental results show that the controller has high response efficiency and anti-interference.
