摘　　要：针对智能车间温度控制系统具有大惯性、慢时变等特点,设计了一种模糊单神经元PID控制器。控制系统采用LPC1768作为主控芯片,结合MRF24J40对温度进行无线采集,采用模糊控制和单神经元网络相结合的方法,对PID的3个参数进行动态调整,实现对温度的准确控制。MATLAB仿真结果表明:该控制算法优于传统PID控制和单神经元自适应PID控制,具有很强的自适应性和鲁棒性。In view of the nonlinearity,hysteresis and time-varying of the intelligent workshop temperature control system,a fuzzy single-neuron PID controller was proposed. In the control system,LPC1768 was used as the main chip. Combining with MRF24J40, temperature wireless acquisition was made. A method of combining fuzzy control and single-neuron network was used to adjust the three parameters of PID dynamically to realize accurate control on temperature. The MATLAB simulation results show that this control algo-rithm is superior to conventional PID control and the single neuron adaptive PID control. It has strong adaptability and robustness.
