基于PLC的PID控制算法的设计

PLC-based Design of PID Control Algorithm

针对实际被控对象的时变性和非线性的特点,本文将以PLC为平台进行PID控制器设计.并对PLC设计PID控制器的算法进行了分析与仿真.仿真结果的分析表明:本文所设计PLC实现的PID控制器在鲁棒性能、跟随性能等方面表现出了良好的控制效果.

According to the actual time of the object and the characteristics of variability and non-linear,a PLC-based PID controller was designed.The algorithm of PID controller based on PLC design was analyzed.The simulation results show that the designed PID controller can achieve good robust performance,following ability and anti-interference performance.
