摘要
针对因理论模型建立不准确影响取力发电机励磁控制系统设计的问题,基于现场可编程门阵列(FPGA),应用小信号测试原理,在闭环回路条件下测试系统开环频率特性。设计串联校正控制器以及为给定电压安排过渡过程,通过Verilog硬件描述语言在FPGA中实现相关功能。通过实验比较分析,该方法能够改善车载取力发电机励磁控制系统动态性能。并且该方法利用FPGA可重复编程的特点,调整参数更加便利。
Aiming at the problem that the inaccuracy of the previous theoretical model establishment affects the design of the excitation control system of the force extraction generator.The principle of small signal test is applied to test the open-loop frequency characteristics of the system in the closed-loop circuit based on the field programmable gate array(FPGA).A series correction controller is designed and the transition process is arranged for a given voltage,and the relation function is realized in FPGA through Verilog hardware description language.Through experimental comparison and analysis,this method can improve the dynamic performance of the excitation control system of the vehicleborne force extraction generator.In addition,this method makes use of the repeatable programming characteristic of FPGA which makes it more convenient to adjust parameters.
