Title:
ガスタービン制御方法
Document Type and Number:
Japanese Patent JP4159676
Kind Code:
B2
Abstract:
In a control of a gas turbine having a gas turbine engine, a fuel pump for supplying fuel to the gas turbine engine, a fuel valve, and a motor for driving the fuel pump, the motor or the fuel valve as a subject of control is controlled. (A) The difference between a target torque set by a user and an actual torque of the gas turbine engine is obtained. (B) A fuzzy control value is obtained by executing a fuzzy control algorithm in which the torque difference and a time differential value of the torque difference are set as input variables. (C) A proportional-differential control value is obtained by multiplying the fuzzy control value by a gain set through a simulation in which the fuzzy control value approximates to the proportional-differential control value from the torque difference. (D) An integral control value is obtained from the torque difference. (E) A proportional-integral-differential control value is obtained by adding the proportional-differential control value and the integral control value obtained from the steps (C) and (D), respectively. (F) Driving of the subject of control is controlled according to the proportional-integral-differential control value. (G) The steps (A) through (F) are repeated.
