摘要
介绍模糊理论与PID控制相结合的智能模糊PID控制技术,分析模糊PID控制器的量化因子和比例因子对控制器性能的影响,由此指出常规模糊PID控制器在工业应用的局限性,并提出一种基于相关量化的在线自适应算法。仿真结果表明:在参考输入改变和受控对象参数漂移时,相比常规模糊PID控制器,改进的控制器具有更好的动态和稳态性能。
An intelligent Fuzzy-PID control technology was introduced,and both quantization factor＇s and scaling factor＇s effect on Fuzzy-PID controller were analyzed to have a limitation within general Fuzzy-PID controller figured out and an online self-a daptive control method which based on correlative quantization presented.Simulation results demonstrate that better dynamic and steady control performance can be achieved in comparison with general Fuzzy-PID controller.
