【摘要】 文中在PID控制器的基础上,以误差和误差变化率为输入,利用模糊推理的方法实现了PID参数的在线自动整定。并且在MATLAB下对某导弹触发引信测试系统稳态精度和抗干扰性方面进行了研究,仿真结果表明,参数自整定模糊PID控制优于常规PID控制,具有良好的稳态精度和自适应能力,使系统抗干扰能力提高了20%左右。更多还原

【Abstract】 Based on PID controller and taken error and error change as inputs,a fuzzy inference method is utilized to realize automatic regulation of PID parameters.A missile trigger fuze system is studied in the aspect of steady state precision and anti-jamming with MATLAB.The result of the simulation shows that the parameter self-tuning fuzzy PID control is superior to traditional PID control and it has a better stability and self-adaptive property.Anti-jamming ability of system is improved about 20%.更多还原
