弹载电液舵机的Bang—Bang＋PID双模控制研究

本文结合一弹载电液舵机系统，介绍了电液位置伺服系统的工作原理。经过推导，建立了该舵机的数学模型。在MATLAB／Simulink中搭建了舵机的仿真模型，分别对PID控制和Bang—Bang控制进行了仿真，仿真结果表明这两种控制方法无法获得满意的控制效果。为取得良好的控制效果，将PID控制和Bang－Bang控制相结合，设计TBang-Bang＋PID双模控制器，提高了系统的控制效果。

Study on Bang-Bang+PID Control for Missile Electro-Hydraulic Steering Gear

In this paper, based on a missile electro-hydraulic steering gear, the components and principle of the electro-hydraulic position servo system is introduced. The mathematical model of the steering gear is also established. PID control and Bang-Bang control of the steering gear are simulated by MATLAB software and the simulation results prove that PID control and Bang-Bang control can＇ t obtain satisfactory control effect. In order to get excellent control effect, Bang-Bang＋PID controller is designed to obtain a better control effect than PID control and Bang-Bang control by combining them.
