【摘要】 由于变风量空调系统具有惯性大、时间滞后等特点,单独采用常规PID控制往往效果欠佳。本文借鉴生物免疫反馈机理和模糊控制理论,设计了模糊免疫PID控制器,将模糊免疫算法应用于室内温度控制环节,并运用模糊免疫PID控制技术对温室进行仿真试验。试验结果表明,控制环节的精度、鲁棒性、超调量及调整时间都得到较大改善。更多还原

【Abstract】 Due to the characteristics of variable air volume air conditioning system inertia,time lags,separate conventional PID control is often ineffective.This paper draws on biological immune feedback mechanism and fuzzy control theory to design fuzzy immune PID controller.Then the fuzzy immune algorithm is applied to indoor temperature control link,and the fuzzy immune PID control technology is used for greenhouse simulation.The testing results show that the control aspects of accuracy,robustness,overshoot and the adjustment of time has been greatly improved.更多还原
