摘　　要：针对电厂锅炉主汽压的控制问题,提出了一种基于SOA(搜寻者算法)优化PID控制器参数的控制方法。在该算法中,以主汽压系统输出的误差绝对值时间积分性能指标作为SOA算法的适应度函数,以得到一组PID控制器的优化参数,并用于锅炉主汽压的控制系统中。仿真结果表明,与粒子群算法及遗传算法相比,SOA优化算法具有较佳的寻优能力及优化效率,进而改善了主汽压控制系统的动态性能。Themain stream pressure is an important parameter reflecting the state of boiler operation.For the main stream pressure control system,a method for optimizing the parameters of PID controller based on seeker optimization algorithm( SOA) was proposed.In this algorithm,the time integral of absolute error performance index is taken as the fitness function,and then a set of optimized parameters is obtained.Simulation results show that SOA has better searchingcapability and optimization efficiency compared to particle swarm optimization and genetic algorithms,and can improve the dynamic performance of main stream pressure control system.
