摘　　要：核动力装置蒸汽发生器的水位控制系统,多采用串级三冲量PID控制方案。为了克服传统的控制器参数整定方法的局限性,应用粒子群优化算法对主调节器进行参数整定,获得了相对最优参数。仿真结果表明,与传统整定方法相比,这种参数整定方案得到的控制参数能使水位控制系统具有更好的控制品质。For the control system of nuclear power plant steam generator,three-impulse cascade control system is usually adopted to regulate the water level.In order to overcome the limitations of traditional tuning methods of controller parameter,particle swarm optimization algorithm was applied to the main regulator and obtains optimal parameters relative.Simulation results showed that compared with traditional tuning methods,this tuning method can bring the water level control system much better control quality.
