[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.
