摘　　要：通过对模糊控制和PID控制理论、系统控制性能进行分析,设计了一种模糊PID温室控制系统,可提高温室系统的控制精度和缩短响应时间;采用模糊推理原则获取PID控制输入参数,利用不同的清晰化方案构建4种不同的模糊控制方案,并采用仿真试验的方式将模糊PID控制系统与传统PID控制方式进行对比分析。试验结果表明:模糊PID控制系统的超调量小于20%,明显小于传统PID控制系统28%的超调量;4种模糊PID控制方案中,有两种方案响应时间优于传统PID控制系统。Through the analysis of fuzzy control and PID control theory and system control performance,this paper designs a kind of fuzzy PID greenhouse control system,improves the control precision and control response time of greenhouse system,uses fuzzy reasoning principle to obtain PID control input parameters,uses different clarity schemes to construct four different fuzzy control schemes,and uses simulation test to realize fuzzy PID control The control system is compared with the traditional PID control method.The experimental results show that the overshoot of the fuzzy PID control system is less than 20%,which is obviously less than 28% of the traditional PID control system.Among the four fuzzy PID control schemes,the response time of two schemes is better than that of the traditional PID control system.
