Through the study design based on a nonlinear PID control the controlled series compensation system, which does not rely on the characteristics of the controlled object model, to make up for the traditional linear PID control some shortcomings. The results of the study show that: with the traditional PID control based on linear fixed series compensation system in comparison, based on nonlinear PID control controllable series compensation technology, because in the feedback of the nonlinear combination to make full use of the function, strengthen the system damping, improve the system of the transient stability, and the system robustness and adaptability of has also improved.%通过研究设计一种基于非线性PID控制[1]的可控串联补偿系统,其不依赖于被控对象的模型特点,能够弥补传统线性PID控制[2]的诸多不足.研究结果表明:与传统的基于线性PID控制的串补系统相比较,基于非线性PID控制的可控串补技术,由于在反馈中充分利用了非线性组合的功能,增强了系统的阻尼、改善了系统的暂态稳定性,同时系统的适应性及鲁棒性也有所提高.
