【摘要】 为了使水下试验平台在定向控制时具有较快的响应速度和较高的精度,利用模糊控制理论设计模糊PID控制器。在设计中讨论了模糊PID控制器的结构和PID参数的整定方法,同时在MATLAB中对模糊PID控制器和PID控制器进行了仿真。通过比较两种控制的仿真结果,表明了模糊PID控制无论在响应速度、超调量还是在稳定误差等方面均优于PID控制。更多还原

【Abstract】 A fuzzy-PID controller was designed for the faster response speed and high accuracy in the heading control of underwater test platform through fuzzy control theory.In the design,the structure of the fuzzy controller and the tuning method of the PID parameters were discussed.The fuzzy-PID controller and the conditional PID controller were modeled and simulated in MATLAB.The comparison of simulation results showed that the fuzzy PID control is superior to the traditional PID control,which can effectively improve the response speed,shorten rise time and reduce the overshoot.更多还原
