基于Proteus的变增益单神经元PID控制仿真研究

摘要

Based on Proteus embedded system software and hardware simulation platform, a new method was put forward to automatic control system simulation. In the example, ATmega 128 worked as microprocessor. Periph- eral circuit used D/A and operational amplifier. The control circuit simulation principle diagram was designed. Two control algorithms using C language programming realized the PID and variable gain single neuron PID re- spectively. The convenience and validity of control system design and simulation under the environment of Pro- teus is illustrated.%基于Proteus嵌入式系统软硬件仿真与开发平台的功能，提出了新的用于自动控制系统的仿真方法．实例中以ATmegal28作为微处理器，外围电路使用D／A、运算放大器等元件，设计了控制电路仿真原理图，软件上采用C语言编程实现了PID与变增益单神经元PID等两种控制算法，最后进行了系统仿真试验．研究表明：基于Proteus的仿真方法能体现控制系统运行的直观性与高效性，突出其在实际设计方面的辅助作用．
