There are many adjustable parameters in the control method of predictive sliding mode control(PSMC) law and linear extended state observer(LESO) for hypersonic vehicle speed and altitude,and the adjustable parameters influence each other on the control effect,and the speed and altitude channels of the aircraft are coupled with each other,so the controllerparameters cannot be independently tuned.A method of automatically tuningcontrollerparameters by using grey wolf optimization(GWO) algorithm is ***,the fitness function containing the desired control effect is designed,and then the appropriate number of search agent and iteration times are *** simulation results show that the control effect of the controller with GWO tuningparameters is obviously better than that of the controller with experience tuningparameters,and the expected control effect can be achieved under the condition of adding parameter deviation and actuator limitation.
