An adaptive fuzzy sliding mode control method for starting speed of marine gas turbine
In the complex and ever-changing offshore operating environment,in order to reduce the response lag time during the start-up process of ship gas turbines,effectively suppress external interference,and ensure that the speed can quickly reach and stabilize to the set value,a self-adaptive fuzzy sliding mode control method for the starting speed of ship gas turbines is proposed.The mathematical model of Marine gas turbine is established by Rowen model.Based on the model,the adaptive fuzzy sliding mode control algorithm is used to design the starting speed controller of Marine gas turbine.The adaptive fuzzy PID algorithm in variable theory domain is used to output the adaptive parameters of the sliding mode con-troller according to the real-time speed deviation and its rate of change,which can be used to adjust the behavior of the slid-ing mode controller to restrain the external interference better.According to the adaptive parameters,the sliding mode con-troller designs the control law to realize the fast response of the starting speed of Marine gas turbine and reduce the response lag time,so that the speed can quickly reach and stabilize to the set value.Experimental results show that this method can ef-fectively and quickly control the starting speed of Marine gas turbine,and the overshoot of the starting speed control is small under load disturbance.
