中文摘要
      大容积环境温度模拟系统具有非线性、大时间常数和慢时变等特点,常规的控制方法难以获得满意的控制效果.本文提出了一种三段式控制策略,在远离设定值时采用Bang-Bang控制或分段逼近控制,以实现控制的快速性;在接近设定值时应用神经网络进行过渡控制,以抑制超调;在达到设定值时采用神经网络PID控制,以克服慢时变漂移,同时给出了各段的控制算法和转换公式.经实际应用证明本文提出的方法是有效的.
英文摘要
      Nonlinearity,big time-constant and slow time-variation are some characteristics of large volume temperature simulating system,and it is difficult to get a perfect result through normal control method.A new control method consists of three phases is presented in this paper.When the temperature is far away from the target,Bang-Bang control is applied so as to achieve fast control.When it is close to the target,neural network control is used in order to restrain overshooting.Once it arrives at the target,PID control is adopted to overcome the effect of slow time-variation.In addition,the control and switching algorithms of each phase are also established.Finally,a practical application example is given to prove the effectiveness of the proposed approach.
