Aiming at the non - linear links such as time lag , inertia , dead time and saturation within the turbine regulating system , a fuzzy - immune - pid control system was designed based on a mutative scale chaos optimization method , the principium of immune feedback system and the theory of fuzzy control 摘要针对汽轮机调速系统中存在的时滞、惯性、死区和饱和等非线性环节,采用模糊控制理论,结合免疫反馈机理,设计了基于变尺度混沌优化策略的模糊免疫pid控制系统。
