摘要
针对常规PID对非线性、时延对象控制参数难以整定的问题,根据偏差和偏差变化率来实时调整PID参数,设计了基于模糊控制原理的PID参数自整定控制器。仿真结果表明,模糊自整定PID控制器比常规PID控制器有更好的控制效果,大大改善了系统的动态和静态性能。
Three-tank water is a typically non-linear and delayed plant, and has strong background of industry. The control parameters of regular PID are difficult to determine on non-linear and delayed plant. Self-tuning PID controller based on theory of fuzzy control is designed by the adjustment of parameter. The results of simulation show that fuzzy self-tuning PID controller is better than regular PID controller, the dynamic and static properties of the control system are improved.
