摘　　要：针对吊舱推进器安装平台四缸同步运动过程中缺乏有效控制策略的问题,提出基于BP神经网络的主从同步控制策略。通过对安装平台顶升液压系统进行分析,推导出四缸同步控制系统的数学模型。根据该数学模型设计基于BP神经网络的PID控制器,并通过AMEsim与MATLAB的联合仿真求解液压系统的同步控制精度。仿真结果表明,该控制策略能有效实现四缸同步运动控制,且同步精度达到±0.1 mm。Aiming at the problem of the lack of effective control strategies during the four-cylinder synchronous movement of the pod thruster installation platform, a master-slave control strategy based on BP neural network is proposed. The mathematical model of the four-cylinder synchronous control system is deduced by analyzing the hydraulic jacking system of the installation platform. The PID controller based on BP neural network is designed according to the mathematical model, and then the synchronous control precision of the hydraulic system is solved through the joint simulation of AMEsim and MATLAB. The simulation results show that the control strategy can effectively realize the four-cylinder synchronous motion control, and the synchronization accuracy can reach ±0.1 mm.
