舰船电机是保证舰船作战能力的重要组成部分，交流异步电机在舰船中使用最为广泛，传统的PID及模糊PID调速都严重依赖专家经验，容易出现电机调速时间过长和超调的问题。本文在传统遗传算法上进行改进，建立了模糊PID的基本结构，并在此基础上提出了改进遗传算法的模糊PID模型，使用Matlab对建立的模糊PID控制和改进遗传算法模糊PID控制进行仿真测试，结果表明改进遗传算法模糊PID控制能够缩短超调量和超调时间，收敛速度有所提升。
The ship motor is an important part to ensure the combat ability of the ship, AC asynchronous motor is the most widely used in the ship, the traditional PID and fuzzy PID speed regulation are heavily dependent on expert experience, easy to appear motor speed regulation time is too long and overfire problems. This paper improves the traditional genetic algorithm, establishes the basic structure of fuzzy PID, and proposes the fuzzy PID model of improved genetic algorithm on this basis. Matlab is used to conduct simulation tests on the established fuzzy PID control and the improved genetic algorithm fuzzy PID control. The results show that the improved genetic algorithm fuzzy PID control can shorten the overshoot amount and overshoot time, and improve the convergence speed.
