摘要
讨论了水轮机调速器PID控制、自适应控制和几种智能控制及非线性鲁棒控制的优缺点,指出了神经网络控制、模糊控制和PID控制相结合可以实现PID控制器参数的在线调整.针对经典的PID调节,利用改进遗传算法对参数进行了优化,实现PID参数快速调整.非线性鲁棒控制是针对水轮发电机组的非线性化模型设计的,可有效改善水电厂远距离输电系统的运行安全性,提高输电系统的传输功率.
The advantages and disadvantages of PID control,adaptive control,intelligent control and nonlinear robust control used in turbine governors were discussed,and it was pointed out that the PID controller parameters could be adjusted online if the neural network control,fuzzy control and PID control were combined with each other.For the classical PID regulator,its parameters could be adjusted rapidly if the parameters were optimized by the improved genetic algorithm.Nonlinear robust control was designed for the nonlinear model of the hydrogenerator unit,which could effectively improve the safety of long-distance transmission systems and enhance the transmission power of transmission systems.
