Abstract:

Aiming at the situation that the antenna servo system of XX equipment developed by trial and error method cannot obtain the optimized PID parameters, the PID parameter optimization of the servo system of the equipment is studied. Start with the device's original data and instructions, analyze the composition principle of the device, the performance of each component, and the mechanism of the specified angle tracking of the antenna servo system. Second, consult the relevant data, analyze the transfer function model of the key components of the system to model the entire antenna servo The system optimizes the parameters of the antenna servo system from the three-loop structure of the system in accordance with the principles of engineering design. Finally, Matlab/Simulink software is used to simulate and analyze the optimized servo system. The simulation analysis results show that the step dynamic response performance of the overall antenna servo system after engineering design optimization is better than the current antenna servo system performance. This method theoretically provides a certain guiding role for the optimization of the control performance of the antenna servo system, and provides a certain practical value for the optimization and performance improvement of the equipment.
