Application in Fluid Furnace Control of PID Parameter Tuning Based on GA

以IAE为优化目标,将遗传算法优化PID参数,应用于一单容水箱的液位控制系统中,并给出了算法的仿真结果。研究表明,遗传算法得到较好性能指标的搜索结果,对参数整定优化策略具有很强的灵活性、适应性和鲁棒性,具有一定的推广应用价值。

By taking IAE as objective function,GA(Genetic Algorithm) is used in a fluid furnace control system to tune PID parameters,and giving the simulation results.Research shows that the GA gets a better PID parameters optimization result based on IAE index,and it has excellent flexibility,adaptability and robustness,and has the certain expansion application value.
