摘要
微型燃气轮机的燃料压力系统是燃气轮机的重要组成部分,针对燃气轮机正常工作时燃料储罐里面的燃料压力应当恒定的要求,提出了模糊PID控制方法。在调试初期,燃料压力控制采用传统的PID进行控制和调节。由于存在干扰,控制效果不很理想。在传统的PID控制下加入模糊控制,使其PID参数有在线自整定功能。通过Matlab仿真表明,该方法比传统的PID控制效果有明显改善。
The fuel pressure control system of a micro turbine is an important component of the turbine. Since the parameters of fuel pressure in the fuel-storing tank must be kept constant to make the micro turbine work normally, the scheme for pressure control using fuzzy-PID algo-rithm is proposed. At the beginning of debugging, the fuel pressure is controlled and adjusted by traditional PID control. Owing to the disturbance, the control result is always out of acceptance, so fuzzy control is presented into the traditional PID control, which makes the parameters of PID be adjusted on-line, The Matlab simulation results show that the proposed algorithm works effectively than traditional PID control,
