摘要
针对工业过程控制中传统PID控制器存在的问题,将参数自整定模糊控制的灵活性、自适应性与传统PID控制器相结合,实现了对PID参数的在线自动整定,以克服控制系统的大滞后、非线性等不利因素的影响,并且将该控制器在温度控制系统中的应用进行了研究。结果表明,参数自整定模糊PID控制能使系统达到满意的控制效果,具有一定的应用推广价值。
It is hard to get ideal control effect with traditional PID in process control. This paper presents a controller by combining autotuning fuzzy control with traditional PID control. The fuzzy inference method is used to tune the PID parameters. It can conquer the influence of nonlinear and large delay in process control system. And it is applicable to temperature control system. Experiment shows that the controller gives a good control performance.
