Abstract | The invention provides a main steam pressure control method based on fuzzy control, which is mainly characterized in that a designed fuzzy PID (Proportion Integration Differentiation) controller is of a double-input three-output controller structure, the input is an error e and the variation ec of the error, and the output is the variation of three PID coefficients Kp, Ki and Kd. Wherein the variable quantity ec of the error is added to the input side to judge the change direction of the error in the process so as to improve the rapidity of system response, and scale transformation is carried out on the processed input quantity to enable the processed input quantity to be transformed into the respective discourse domain range. According to the actual engineering experience of a controlled object, a control rule table of three outputs of dKp, dKi and dKd is obtained, a fuzzy quantity output value is obtained after a fuzzy language value is subjected to reasoning synthesis of a control rule, a value on a fuzzy |
