4) PI parameters
PI参数
1.
A systemized optimization method for PI parameters of HVDC controller is proposed.
首先根据Bode图求出满足系统稳定性要求的PI参数范围;再对该参数范围按一定步长进行划分,得到有限组PI参数以构成PI参数寻优的样本集;对应每一个样本参数仿真计算控制器的阶跃响应, 并按时间乘绝对误差积分(integral of time multiplied by the absolute value of error,ITAE)准则计算目标函数值;取对应 ITAE目标函数值最小的样本参数为最优PI参数。
2.
The system not only improve the high-frequency switching problem brought by conventional hysteresis control strategy,but also adopts load current feed-forward control to make the system has much lower dependence on the PI parameters of the outer voltage regulator than conventional hysteresis current control PWM rectifiers.
该系统不仅改进了传统滞环控制策略带来的高开关频率的问题,更引入了负载电流前馈控制,使得系统对于外环的PI参数有着较传统滞环PWM整流器更低的依赖性,在三相电网不平衡的条件下也表现更好的运行特性。
