摘　　要：文章提出一种基于遗传算法优化的模糊PID恒温水浴控制系统。遗传算法通过编码、构造适应值函数、选择、交叉和变异优化得到模糊PID控制中的模糊控制规则表,以实现精准控制恒温水浴的温度。系统仿真结果表明,所提出的温度控制系统不仅能够提高调控的速度,而且保证调温过程的稳定性。For this paper,we propose a constant temperature water bath control system by fuzzy PID,which utilizes Genetic Algorithm to optimize its fuzzy control rule table.In the optimization method,we adopt a binary coding method to encode the fuzzy control rule table and establish a fitness function using control time.Then,we optimize the fuzzy control rule table using selection,crossover,and mutation to achieve precise temperature control.The system simulation results show that the proposed temperature control system can improve the speed of regulation and ensure the stability of the temperature regulation process.
