大功率四極管調制器的特性分析及控制研究

摘要：本文研究了HL-2A裝置中大功率四極管調制器的特性，提出一種根據四極管調制器的恒流曲線，對其進行線性插值擬合的建模思路，并得到有效的調制器數學模型。在這種模型的基礎上，研究了調制器控制的閉環反饋策略，驗證了PI反饋控制作為HL-2A裝置中大功率四極管調制器的控制策略是合適的。 敘詞：大功率四極管調制器 線性插值 數學模型 Matlab/simulink PI反饋 Abstract：In this paper, High-power Tetrode modulator characteristics of the HL-2A device are analyzed. Based on the constant current curve of High-power Tetrode modulator ,presents a thought of modeling a mathematical model by linear interpolation.The mathematical model is efficacious. Study the closed-loop feedback strategy of the controller of High-power Tetrode modulator using the mathematical model of High-power Tetrode modulator.Finally validated that the PI closed-loop feedback controlling strategy of High-power Tetrode modulator is correct and appropriate.
