摘要 提出一种基于前馈控制和变论域模糊控制的联合装置温度控制器设计方法。在该方法中,采用优化的比例指数型伸缩因子,对温度的模糊变量论域进行变换,实现了温度环的自适应控制,采用基于扰动的前馈补偿很好的抑制了温度的波动。利用S函数编程设计了联合装置变论域自适应模糊温度控制器,并进行了联合装置温度控制器的仿真实验。仿真结果表明,与传统的PID控制相比,基于前馈控制和变论域模糊预测控制的联合装置温度控制器具有较强的抗干扰性和鲁棒性,可以提高联合装置内反应的效率,扩大效益。 Feedforward and variable region fuzzy controller of temperature of complex unit is proposed. In this method, the uni-verse of discourse of the temperature fuzzy variables are converted adopting optimized proportional exponential contraction-expan-sion factor. The adaptive control of temperature is achieved. Temperature fluctuation is very good restrained using feedforward com-pensation based on disturbance. The adaptive fuzzy temperature controller with variable region of complex unit is designed using S-Function programming. The simulation experiment of it is done. The simulation results show that compared with traditional PID control, temperature controller based on feedforward and variable region fuzzy has the strong anti-interference performance and ro-bustness. It can improve the reaction efficiency of complex unit and expand benefits.
