摘要
针对发电用单轴微型燃气轮机这样大型复杂且具有极强非线性的热能动力系统,提出了适用的燃机转子转速自适应模糊控制方法,将加速度限制包含在规则中,从而构建了新的控制结构。理论证明,利用在线调整算法改变模糊规则基使控制系统达到了全局稳定。数据仿真表明,控制方案对燃气轮机的转速控制取得了很好的效果,具有实际应用价值。方法适用于提出的一类具有单输入单输出的非线性系统。
An adaptive fuzzy control approach to the rotation speed of a micro gas turbine, the thermodynamic system that is complex and exceedingly nonlinear, was proposed. A novel control structure and algorithm was established by including limitation of rotor acceleration in the fuzzy rules. Theory proves that the algorithm of on-line self-adjusting used to alter the fuzzy rule bases makes the control system of gas turbine stable globally. The results of simulation show that the scheme and algorithm can work effectively and can be available for a class of SISO nonlinear system.
