Study on Adaptive PID Controller of HSVS Based on Modified Simplex Method
摘要
结合机械投切电容器(MSC)、晶闸管投切电容器(TSC)及晶闸管相控电抗器(TCR)特性

使MSC、TSC、TCR分别工作在粗调、细调和精调的工作模式。为解决PID控制对这三者的配合问题
提高控制精度与系统鲁棒性
引入了单纯形算法作为PID参数的学习函数
并对单纯形算法的步长调整以及测度引入加以改进。仿真实验证明
与普通的自适应PID控制器相对比
改进了单纯形算法的自适应控制在混合型无功补偿系统电压控制中的可行性与高效性
提高了补偿精度与适应性。
Abstract
In this paper
a new type of hybrid static reactive power compensation system( HSVS) is designed based on the characteristics of MSC
TSC and TCR so to keep MSC
TSC and TCR work at rough
fine and very fine tuning respectively. For solving coordination problem of PID control among them
improving control accuracy and system robustness
learning function is introduced into the simplex algorithm as a PID parameter
the step adjustment and measurement introduction of simplex algorithm is improved. It is shown by simulation test that compared with general adaptive PID controller
it improved feasibility and high efficiency of adaptive control of simplex algorithm in the voltage control of hybrid reactive compensation system and enhances compensation accuracy and adaptability.
