摘　　要：首先,针对传统比例-积分-微分(PID)控制系统中存在的调节时间长、时延、滞后等问题,提出使用改进的饥饿游戏搜索(THGS)算法优化传统PID控制器的参数.其次,利用作物生长模型、土壤水分传输模型和土壤肥料传输模型进行仿真实验.结果表明,THGS算法优化的PID控制器在调节时间和起调量方面均优于其他控制器,有效提升了控制系统的性能.Firstly,aiming at the problems of long adjustment time,delay and hysteresis in the traditional proportional integral derivative(PID)control system,we proposed using the improved hunger games search(THGS)algorithm to optimize the parameters of the traditional PID controller.Simulation experiments were carried out by using crop growth model,soil moisture transport model and soil fertilizer transport model.The results show that the PID controller optimized by THGS algorithms is superior to other controllers in terms of adjustment time and starting amount,which effectively improves the performance of the control system.
