摘要
针对火电机组锅炉汽包水位控制系统性能优化问题,提出一种用于优化其控制参数的改进遗传算法.对某汽包水位串级三冲量控制方案的研究表明:无论在无扰动实验还是给水扰动、蒸汽扰动实验中,改进遗传算法响应曲线的滞后时间、上升时间、调节时间、超调量都明显优于参比法和标准遗传算法.
Aiming at the optimization of control performance of boiler drum water level control system for thermal power unit boiler, a method of optimizing controller parameters by improving genetic algorithm is proposed. A comparative study on the cascade control scheme of a steam drum water level indicates that the improved genetic algorithm control performance is significantly better than the reference method and the standard genetic algorithm. In the comparative experiment, the lag time, rise time, adjustment time and overshoot of the improved genetic algorithm response curve is significantly better than the reference method and the standard genetic algorithm.
