【摘要】：在大型电力机组温度过热的控制中,传统的控制方法较为烦琐。针对这一问题,提出了一种PID和模糊控制原理相结合的控制方法,通过该方法设定大型电力机组温度过热给定值偏差的范围,以模糊集合论、模糊语言变量描述和模糊逻辑推理为基础进行控制。在无需建立被检测对象准确数学模型的前提下,对不确定性和非线性温控系统进行控制。该方法对大型电力机组系统参数变化控制有较强的鲁棒性,有较强的抑制干扰能力。仿真的结果表明,该控制方法与传统的控制方法相比,在大型电力机组温度过热控制中具有响应快、稳定性高、工作效率高和鲁棒性强等特点。
[Abstract]:In the control of large power unit temperature overheating, the traditional control method is rather cumbersome. In view of this problem, a control method combining PID and fuzzy control principle is proposed. Through this method, the range of deviations of the given values of temperature overheating of large power units is set up, and the fuzzy set theory is used. Fuzzy language variable description and fuzzy logic reasoning are used as the basis of control, without the need to establish an accurate mathematical model of the detected object. The uncertain and nonlinear temperature control system is controlled. The method is robust to the parameter change control of large power unit system and has a strong ability to suppress interference. The simulation results show that the proposed method is robust to the control of large power unit system. Compared with the traditional control method, this control method has the characteristics of fast response, high stability, high working efficiency and strong robustness in large power unit temperature overheating control.
