In order to win future high-tech local wars and improve military combat capabilities,highmaneuverability and high-precision combat devices have gradually become the focus of research.Rocket launcher is a typical electromechanical servo system,but there are factors such as parameter determination,external interference,and two-axis coupling during its movement,which restrict the improvement of the servo system's performance.How to improve the rapidity of the rocket launching platform to aim at the target,reduce the initial disturbance of the kinetic energy load launch,and improve the stability of the system under the impact of the launching impact load,has gradually become the focus of research.This paper focuses on the rocket launcher electromechanical servo system as the research object,mainly from the following aspects:1.Introduce the system composition of the electromechanical servo system of the rocket launcher,combine the dynamic equation of the permanent magnet synchronous motor,and consider the coupling torque,gas flow impact,and friction torque,and further establish the twoaxis coupling dynamics model of the motor servo system.2.Combining fuzzy control and traditional PID control,using the learning ability of fuzzy control to make up for the disadvantage that the three parameters of traditional PID control cannot be adaptive when the working conditions change,and effectively improve the system's adaptive ability and stable tracking accuracy.3.Many controllers are designed to use full-state feedback control methods,but in the launching reality system,the state velocity is difficult to obtain.This paper designs a sliding mode state observer to estimate state variables.In addition,considering the severe conditions of the transmitter's harsh environment,such as time-varying nonlinear parameters,interference,and input saturation,a research on adaptive robust composite control strategy based on fuzzy interference compensation is designed to improve the control accuracy and performance of the electromechanical servo system.4.The effectiveness of the rocket launcher electromechanical servo control algorithm designed in this paper is verified through theoretical analysis and simulation.The experimental research further verifies the control method and simulation results of this time,and provides experimental basis for the follow-up research on the electromechanical servo control system of the rocket launcher.
