摘要
船舶燃气轮机对转速的要求较高,需在瞬间完成响应并保持稳定。然而,由于燃气轮机具有惯性和时间延迟等特性,导致转速的调整可能存在响应滞后或者波动问题。为此,提出基于状态观测的船舶燃气轮机转速自适应模糊控制方法。应用船舶燃气轮机转速状态观测器,结合船舶燃气轮机转速与燃油量之间的映射关系,根据当下燃油量状态,观测实际船舶燃气轮机转速,通过基于模糊自适应PID控制器的转速控制模型,计算实际转速与给定转速的转速偏差、偏差率,由模糊自适应PID控制器自适应调节船舶燃气轮机转速。实验结果证明:此方法应用下,船舶燃气轮机转速能够得以准确控制。
Marine gas turbines have high requirements for speed and need to respond in an instant and maintain stability.However,due to the inertia and time delay characteristics of gas turbines,the adjustment of speed may have the problem of response lag or fluctuation.Therefore,an adaptive fuzzy control method for Marine gas turbine speed based on state observation is proposed.Based on the mapping relationship between ship gas turbine speed and fuel amount,the actual ship gas turbine speed is observed according to the current fuel amount state by applying the ship gas turbine speed state observer,and the speed deviation and deviation rate between the actual speed and the given speed are calculated through the speed control model based on the fuzzy adaptive PID controller.The speed of Marine gas turbine is adjusted adaptively by fuzzy adaptive PID controller.Experimental results show that the speed of Marine gas turbine can be controlled accurately with this method.
