摘　　要：中国环流器2号(HL-2A)装置的等离子体低混杂波辅助加热系统的脉冲高压电源的输出电压,在投入负载的过程中会有一定程度的跌落,并且当前级电源-125MVA 脉冲发电机的其他负荷发生变化时,其输出电压也会发生变化。利用 MATLAB 进行数字仿真之后,对该电源系统采用了 PID 反馈控制与前馈补偿策略,其实际应用结果表明,该控制策略能很好地满足该电源电压稳定性的要求。The output voltage of the pulse high voltage,power supply of the low hybrid heating system for the HL-2A Tokamak will de- cline to a certain extent as the load of the klystrons is connected to it.and it will also change while the other loads of its preceding pow- er supply of 125MVA M-G set change.After a simulation using MATLAB.a strategy of PID feedback control and feed-forward com- pensation is used for this power supply system.The experiment results shows that the strategy designed according to the simulation can meet the requirements of the voltage stability of the power supply very well.
